Description

Technical Field

[0001] The utility model relates to the technical field of roll changing devices, in particular to an automatic roll changing device for high-weight paper strips. Background Art

[0002] After passing through the drying section of a paper machine, the paper sheets are wound into rolls on a winder. When the rolls meet the reeling requirements for the next process, rewinding, the rolls need to be changed. When changing rolls, the paper sheets need to be re-pulled onto the next reel to complete the reeling and changing. Manually changing rolls for high-weight paper is particularly difficult, and uneven winding of the reel can easily cause the paper sheets to fold. Rewinding takes a long time, and can even cause paper breaks due to roll changes, requiring re-threading operations, thus affecting the papermaking efficiency of the papermaking machine. In specific production applications, due to order-based production, production plans are determined by market and customer demand, and the variety and quantity of paper must be changed frequently. The paper machine speed and related process parameters need to be adjusted accordingly. Especially when making high-weight paper, folds or breaks due to roll changes require re-threading, which leads to increased paper waste and indirectly affects the energy consumption of the product.

[0003] The prior art discloses a patent with publication number CN107499998A, which includes a paper reel drive device and a paper reel brake device; the paper reel drive device includes a drive motor, a drive wheel, a motor bracket and a paper reel, and the rotation of the drive wheel drives the paper reel matched therewith to rotate; the paper reel brake device includes cylinder I, cylinder II, a support frame, hand grip I and hand grip II, and the movement of the telescopic rod of the cylinder drives hand grip I and hand grip II to open and close; the paper reel includes a frame, a paper reel cylinder, a paper reel, cylinder III, a transmission connection device and a swing arm, and the paper reel is provided with a quick paper reel replacement device; by arranging the paper reel drive device and the paper reel brake device on the paper reel, the rolling quality is improved.

[0004] The existing devices including the above patents have gradually exposed the shortcomings of the existing technology as they are used, mainly in the following aspects:

[0005] First, the existing automatic roll-changing device is provided with a paper tape guiding mechanism, which guides the paper tape for paper feeding. The existing guiding structures all use guidance to transport the paper tape, which causes the guide wheel paper tape to always be in contact with the guide wheel. When impurities adhere to the guide wheel, causing the wheel surface to be uneven, it will leave indentations on the surface of the paper tape, affecting the surface quality of the paper tape.

[0006] Second, the existing guide mechanism has a fixed direction and cannot meet the requirements of different paper winding machines for different paper winding heights, thereby reducing the scope of use.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0008] In response to the defects in the existing technology, the utility model provides an automatic roll-changing device for high-weight paper tape, which is used to solve the problem that the automatic roll-changing device in the traditional technology is provided with a paper tape guiding mechanism, and the paper tape is guided to feed paper through the paper tape guiding mechanism. The existing guiding structures all use guidance to transport the paper tape, which causes the guide wheel paper tape to always be in contact with the guide wheel. When impurities adhere to the guide wheel, causing the wheel surface to be uneven, it will leave indentations on the surface of the paper tape, affecting the surface quality of the paper tape.

[0009] To achieve the above objectives, the present invention provides the following technical solutions:

[0011] The guide shell is opened at both ends, and two fixed positioning plates that move toward and oppositely are arranged side by side in the guide shell. Two guide positioning plates that move toward and oppositely are also arranged on one side of the fixed positioning plate.

[0016] As an optimized solution, the guide housing is provided with a rectangular sliding hole communicating with its inner cavity, and the guide seat is fixed with a guide block which is slidably constrained in the rectangular sliding hole.

[0017] As an optimized solution, screws are rotatably provided on the opposite outer walls of the guide housing, and the guide seat is threadedly connected to the screws.

[0020] As an optimized solution, the telescopic end of the second cylinder is fixedly connected to a connecting rod, and the connecting rod is fixedly connected to the back surface of the guide positioning plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] When the paper tape needs to be guided, one end of the paper tape is extended into the guide housing, and after the paper tape is clamped by the two guide positioning plates, it is guided and transported toward the other end of the guide housing by the lead screw. When the two guide positioning plates move to the extreme position, the two fixed positioning plates clamp and position the paper tape to prevent the paper tape from escaping from the guide housing. After the two guide positioning plates are reset, they clamp the paper tape again, the two fixed positioning plates are released, and then the two guide positioning plates are guided and transported toward the other end of the guide housing again, and the cycle is repeated in sequence to achieve guided feeding of the paper tape.
