Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fixed-distance cutting device for packaging bag production, and in particular to a fixed-distance cutting device for new material packaging bag production. Background Technology
[0002] As market demand for packaging bags continues to increase, businesses need to improve production efficiency. In traditional cutting equipment, changing and adjusting the cutting blades is a complex and time-consuming process. Taking the production of plastic packaging bags of different sizes as an example, when it is necessary to switch from producing large-size packaging bags to small-size packaging bags, it may be necessary to replace the entire cutting blade assembly or make fine adjustments to the blade position.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: When the fixed-distance cutting device cuts the packaging bag body, because the packaging bag body is made of plastic material with a certain degree of toughness, when the packaging bag body is in a rolled state for a long time, it will curl up inside and contain a certain amount of gas. As a result, during the fixed-distance cutting process, the cutting device is difficult to cut accurately according to the preset position and size, resulting in uneven lengths or crooked cuts. Therefore, a new fixed-distance cutting device for the production of packaging bags is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where, when a fixed-distance cutting device cuts the packaging bag body, the plastic material itself has a certain degree of toughness. When the packaging bag body is rolled up for a long time, it will warp up and contain some gas. This makes it difficult for the cutting device to accurately cut according to the preset position and size during the fixed-distance cutting process, resulting in inconsistent lengths or crooked cuts. Therefore, this invention proposes a new fixed-distance cutting device for the production of packaging bags.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixed-distance cutting device for producing new material packaging bags, comprising an operating table, a packaging bag body slidably connected to the surface of the operating table, an adjustment device provided on the surface of the operating table, the adjustment device comprising two fixed frames, both fixed frames being fixedly connected to the surface of the operating table, a slider slidably connected to the inner surface of the fixed frame, a fixed rod fixedly connected to one side of the two sliders that are close to each other, a hollow tube rotatably connected to the arc surface of the fixed rod, a threaded rod threadedly inserted into the fixed frame, a round block fixedly connected to one end of the threaded rod, and a slider rotatably connected to one end of the threaded rod.
[0006] The effect achieved by the above-mentioned components is as follows: by setting the adjustment device, the packaging bag body is compacted, which avoids the situation where the packaging bag body is made of plastic and has a certain degree of toughness. When the packaging bag body is rolled up for a long time, it will curl up and contain a certain amount of gas. This will make it difficult for the cutting device to make accurate cuts according to the preset position and size during the fixed-distance cutting process, resulting in uneven lengths or crooked cuts.
[0007] Preferably, a spring is fixedly connected to one side of the slider, and the other end of the spring is fixedly connected to the inner surface of the fixing frame.
[0008] The effect achieved by the above components is that the spring buffers the hollow tube, prevents the hollow tube from becoming unstable, and makes it easier to compact the packaging bag body before cutting.
[0009] Preferably, two guide frames are fixedly connected to the surface of the operating table, and the inner surface of the guide frames is slidably connected to the packaging bag body.
[0010] The effect achieved by the above components is to pre-process and straighten the packaging bag body to prevent the packaging bag body from folding and bending before cutting, which would result in the packaging bag body failing to meet the cutting standards.
[0011] Preferably, the surface of the operating table is provided with a groove, and a setting rod is fixedly connected to the inner surface of the groove. A rubber rod is rotatably connected to the arc surface of the setting rod.
[0012] The effect achieved by the above components is to reduce the friction between the rubber rod and the packaging bag body and the operating table, making it easier for the packaging bag body to move forward and preventing damage to the packaging bag body.
[0013] Preferably, the surface of the operating table is provided with an auxiliary device, the auxiliary device including an H-shaped frame, the H-shaped frame being fixedly connected to the surface of the operating table, two flat plates being slidably connected to the inner surface of the H-shaped frame, two fixing plates being fixedly connected to one side of the flat plates, a screw being threaded into the fixing plate, and a sliding plate being rotatably connected to one end of the screw.
[0014] The effect achieved by the above-mentioned components is as follows: by setting up auxiliary devices, it is possible for workers to collect various types of packaging bags, avoiding the need for complex operations such as stopping the machine when collecting packaging bags. When the packaging bags accumulate to a certain thickness on the plate, workers need to stop the machine, place the packaging bags in a designated location, and then restart the machine to produce another type of packaging bag. This results in frequent machine start-ups and shutdowns and intermediate processing steps every time the type of packaging bag is changed, which not only increases the complexity of the operation process, but also interrupts continuous production, consumes extra time, and thus reduces overall production efficiency.
[0015] Preferably, two guide rods are slidably connected inside the fixed plate, and one end of each guide rod is fixedly connected to the sliding plate.
[0016] The effect achieved by the above components is that the rotating screw rotates inside the sliding plate, the screw drives the sliding plate to move, and the guide rod drives the sliding plate to move, thus avoiding the situation where the sliding plate rotates along with the screw.
[0017] Preferably, a square rod is fixedly connected to one side of the H-shaped frame, and a sliding insert rod is slidably connected to the surface of the square rod. A limit frame is fixedly connected to one side of the flat plate, and a plurality of limit holes are provided on one side of the limit frame.
[0018] The aforementioned components achieve the following effect: they limit the height of the plate, and when the packaging bags are stacked, the height of the plate is adjusted to collect more packaging bags.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting an adjustment device, the packaging bag body is compacted, which avoids the situation where the packaging bag body is made of plastic and has a certain degree of toughness. When the packaging bag body is rolled up for a long time, it will curl up and contain a certain amount of gas. This makes it difficult for the cutting device to make accurate cuts according to the preset position and size during the fixed-distance cutting process, resulting in uneven lengths or crooked cuts.
[0021] 2. In this utility model, by setting an auxiliary device, the staff can collect various packaging bag bodies, avoiding the complicated situation of stopping the machine when collecting packaging bag bodies. When the packaging bag bodies accumulate to a certain thickness on the plate, the staff needs to stop the machine, place the packaging bag bodies in a designated location, and then start the machine again to produce another type of packaging bag body. This results in frequent machine start-up and shutdown and intermediate processing steps every time the type of packaging bag body is changed, which not only increases the complexity of the operation process, but also interrupts continuous production, consumes extra time, and thus reduces the overall production efficiency.

[0027] Reference Figure 1 As shown, this utility model provides a technical solution: a fixed-distance cutting device for producing new material packaging bags, including an operating table 1, a packaging bag body 2 slidably connected to the surface of the operating table 1, and an adjustment device 3 provided on the surface of the operating table 1. By setting the adjustment device 3, the packaging bag body 2 is compacted, avoiding the situation where, when the fixed-distance cutting device cuts the packaging bag body 2, the packaging bag body 2 is made of plastic and has a certain degree of toughness. When the packaging bag body 2 is in a rolled state for a long time, it will warp up and contain a certain amount of gas, making it difficult for the cutting device to accurately cut according to the preset position and size during the fixed-distance cutting process, resulting in uneven lengths or crooked cuts. The surface of the operating table 1 is equipped with an auxiliary device 4. By setting the auxiliary device 4, the staff can collect various packaging bag bodies 2. This avoids the complicated situation of having to stop the machine when collecting packaging bag bodies 2. When the packaging bag bodies 2 accumulate to a certain thickness on the flat plate 42, the staff needs to stop the machine, place the packaging bag bodies 2 in a designated location, and then start the machine again to produce another type of packaging bag body 2. This results in frequent machine start-ups and shutdowns and intermediate processing steps every time the type of packaging bag body 2 is changed. This not only increases the complexity of the operation process, but also interrupts continuous production, consumes extra time, and thus reduces the overall production efficiency.
[0028] The specific settings and functions of its adjustment device 3 and auxiliary device 4 will be described in detail below.
[0029] Reference Figure 2 and Figure 3As shown in this embodiment: the adjusting device 3 includes two fixed frames 301, both of which are fixedly connected to the surface of the operating table 1. A slider 302 is slidably connected to the inner surface of each fixed frame 301. A fixed rod 303 is fixedly connected to one side of each slider 302 that is close to the other. A hollow tube 304 is rotatably connected to the arc surface of the fixed rod 303. A threaded rod 305 is threaded into the inner surface of the fixed frame 301. A round block 306 is fixedly connected to one end of the threaded rod 305. The slider 302 is rotatably connected to one end of the threaded rod 305. A spring 307 is fixedly connected to one side of the slider 302, and the other end of the spring 307 is fixedly connected to the inner surface of the fixed frame 301. The spring 307 buffers the hollow tube 304, preventing instability and facilitating compaction before cutting the packaging bag body 2. Two guide frames 308 are fixedly connected to the surface of the operating table 1, and the inner surface of the guide frames 308 is slidably connected to the packaging bag body 2. The packaging bag body 2 is pre-treated to be straight to prevent folding and bending before cutting, which would result in substandard cutting. A groove 310 is formed on the surface of the operating table 1. A setting rod 309 is fixedly connected to the inner surface of the groove 310, and a rubber rod 311 is rotatably connected to the arc surface of the setting rod 309. This reduces friction between the rubber rod 311 and the packaging bag body 2 and the operating table 1, making it easier for the packaging bag body 2 to move forward and preventing damage.
[0030] Reference Figure 3 and Figure 4 As shown, specifically, the auxiliary device 4 includes an H-shaped frame 41, which is fixedly connected to the surface of the operating table 1. Two flat plates 42 are slidably connected to the inner surface of the H-shaped frame 41. Two fixed plates 44 are fixedly connected to one side of each flat plate 42. A screw 45 is threaded into the fixed plate 44, and a sliding plate 43 is rotatably connected to one end of each screw 45. Two guide rods 46 are slidably connected within the fixed plate 44, and one end of each guide rod 46 is fixedly connected to the sliding plate 43. Rotating the screw 45 within the sliding plate 43 causes the sliding plate 43 to move, and the guide rods 46 also cause the sliding plate 43 to move, preventing the sliding plate 43 from rotating along with the screw 45. A square rod 47 is fixedly connected to one side of the H-shaped frame 41, and a sliding insert rod 49 is slidably connected to the surface of the square rod 47. A limit frame 48 is fixedly connected to one side of each flat plate 42, and several limit holes are provided on one side of the limit frame 48. The plate 42 is positioned to limit the height of the packaging bag bodies 2 as they accumulate, thereby collecting more packaging bag bodies 2.
[0031] Working principle: When the staff needs to process the packaging bag body 2, they first open it and place the packaging bag body 2 on the operating table 1 according to the production requirements. The packaging bag body 2 is then passed between the two guide frames 308 and then under the cutter. The threaded rod 305 is rotated in the slider 302, so the slider 302 slides on the inner surface of the fixed frame 301 to compress the spring 307. This causes the fixed rod 303 and the hollow tube 304 to move up and down. The fixed rod 303 and the hollow tube 304 are adjusted to a suitable position to compact the packaging bag body 2. As the packaging bag body 2 moves forward, the rubber rod 311 in the groove 310 rotates.
[0032] When the staff collects the cut packaging bag body 2, they first slide the flat plate 42 in the H-shaped frame 41. When the flat plate 42 reaches the designated position, they pull the sliding rod 49 to slide on the surface of the square rod 47 and insert it into the round hole of the limiting frame 48 to limit the flat plate 42. The cut packaging bag body 2 falls onto the surface of the flat plate 42. When it is necessary to remove it from the flat plate 42, the screw 45 is turned and the sliding plate 43 is moved forward under the guidance of the guide rod 46 to tidy up the uneven packaging bag body 2.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
