When the tension of the bag-making material decreases, the device will immediately increase the tension to prevent the material from loosening, deviating, or breaking. Conversely, when the tension is too high, the device will relax the tension to avoid the material being overstretched or torn. This achieves dynamic balance, significantly reduces the number of downtimes caused by tension problems, improves production continuity, and ensures that the material is always in a stable state, resulting in accurate bag size, firm sealing, and a smooth appearance.

[0024] 2. Through the setting of the conveying and cleaning mechanism, motor one and motor two drive the bag-making raw materials to be conveyed. During the conveying process, the sticking cylinder adheres to and collects the dust on the bag-making raw materials. Then, the dust on the sticking cylinder is collected by the scraper of the dust collection box. In this way, by cleaning the dust, the surface of the raw materials can be kept clean, the sealing performance and appearance quality of the bags can be improved, and the accumulation of static electricity can be reduced, thus reducing the risk of dust adhesion. It is especially suitable for food packaging, pharmaceutical packaging and other fields with high cleanliness requirements. At the same time, it can centrally treat dust, reduce the dust concentration in the air and improve the working environment. Attached Figure Description

A pressure plate 208 is located at the bottom of the sliding rod 206. Pulling the sliding rod 206 causes the pressure plate 208 to disengage from the winding roller 204, and then the bag-making material is pressed under the pressure plate 208. Then, the sliding rod 206 is released, and the sliding rod 206, under the action of the spring 207, presses the bag-making material onto the winding roller 204 for clamping.

[0037] The conveying and cleaning mechanism includes a mounting frame 401, a motor 402, a sticky tube 403, a rotating shaft 404, a mounting assembly, and a switch assembly.

The switch assembly includes a rotating door 411, a pull ring 412, and a locking block 413. The rotating door 411 is rotatably located on the side of the dust collection box 409 away from the adhesive cylinder 403, the pull ring 412 is located on the side of the rotating door 411, and the locking block 413 is located at the end of the rotating door 411.

When the mounting frame 401 is fixed to the outer positioning hole 418, the bag making raw material can be installed. When the mounting frame 401 is fixed to the inner positioning hole 418, the mounting frame 401 on the right side and the adhesive tube 403 can be connected together.

[0038] Example 2

[0039] like Figure 3 As shown, this utility model proposes a tensioning guide device for a bag making machine. Compared with Embodiment 1, this embodiment details the structure of the tensioning adjustment mechanism.

[0040] The tension adjustment mechanism includes a fixed frame 301, a first slide groove 302, an adjusting block 303, and a telescopic rod 304. The fixed frame 301 is located on the side of the mounting platform 1. The first slide groove 302 is located inside the fixed frame 301. The adjusting block 303 is slidably mounted on the first slide groove 302. The bottom of the adjusting block 303 is equipped with a telescopic rod 304, and the outside of the telescopic rod 304 is equipped with a second spring 305. The side of the adjusting block 303 is equipped with a tension roller 306. There are three fixed frames 301. The mounting frames 401 on the left and right sides are lower, and the tension rollers are lower. Position 306 is lower, so the bag-making material is below the tension rollers 306 when passing through them, thus providing upward pressure. Position 301 is higher, and the tension rollers 306 are also higher, so the bag-making material is above them when passing through, thus providing downward pressure. When the tension is too low and the material is too loose, spring 2 305 extends to pull the material on the tension rollers 306. When the tension is too high, the material squeezes the tension rollers 306, causing spring 2 305 to compress, thus preventing the material from being torn.

[0041] In summary, when using this utility model, pull the positioning rod 416 to disengage it from the positioning hole 418, fix the mounting frame 401 in the outer positioning hole 418 to install the bag-making material, and after installation, fix the mounting frame 401 in the inner positioning hole 418. Then, pull the bag-making material to the bottom of the right tension roller 306, the top of the middle tension roller 306, and the bottom of the left tension roller 306, and place it on the take-up roller 204. Pull the sliding rod 206 upward to disengage the pressure plate 208 from the take-up roller 204, and then press the bag-making material under the pressure plate 208. Then, release the sliding rod 206, and the sliding rod 206, under the action of spring 207, presses the bag-making material onto the take-up roller 204 for clamping. Then, start motor 402 and motor 202. Machine 202 drives the take-up roller 204 to rotate via a rotating shaft. During the rotation, the bag-making material is taken up. At the same time, motor 402 drives the adhesive cylinder 403 to rotate via rotating shaft 404. When the adhesive cylinder 403 comes into contact with the knitted fabric, it adheres the dust on the outside of the knitted fabric and scrapes it into the dust collection box 409 as it passes through the dust collection box 409, thus collecting the dust and impurities. After a large amount of dust and impurities are collected in the dust collection box 409, the rotating door 411 is opened by the pull ring 412 to clean out the dust inside. When the tension of the bag-making material is too small, causing the material to be too loose, spring 2 305 extends to tighten the material on the tension roller 306. When the tension is too large, the material squeezes the tension roller 306, causing spring 2 305 to compress, thus keeping the material in a proper tension state.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
