Description

Technical Field

[0001] This application relates to the field of cigarette equipment technology, and specifically to a pressure balancing device for adhesive tape in a YF71 automatic paper roll changing machine. Background Technology

[0002] The YF71 automatic paper roll changing machine primarily provides a continuous and automatic raw material supply system for cigarette machines or filter rod forming machines. It mainly consists of eight parts: paper roll loading, unloading, and filling; paper tape unloading, threading, and splicing; waste paper collection; and inner diameter ring recycling. The YF71 automatic paper roll changing machine primarily provides splicing functionality for running paper tape using adhesive tape. This model uses φ77*120mm, 19mm*19mm edge-perforated automatic adhesive tape. The tape is square, rolled into a cylinder, and unfolded using an adhesive strip picking device. This device removes adhesive strips and supplies them to the bonding device. When the lower paper roll is about to run out, the bonding action allows the upper newly loaded paper roll to supply paper tape to the downstream machine, maintaining the continuity of paper tape supply, and a new adhesive strip is then retrieved. In other words, after splicing, the new tape is adhered to the correct position, preparing for the next splicing. When the tape is picked up, the drive shaft rotates, causing the tape to rotate as well. The tape is kept taut by the pressure rollers, and finally, the tape is adhered to the tape holder. As the tape is used up, the pressure between the tape and the pressure rollers changes, causing a mismatch with the tension generated by the rotation of the drive shaft. This results in the tape being torn and unable to be adhered to the tape holder.

[0003] To address the pressure issue between the tape and the pressure roller caused by tape usage, workers would place a piece of paper at the contact point between the tape and the pressure roller after a certain amount of tape had been used. This would elevate the tape and maintain consistent pressure. However, this method requires constant adjustment of the paper thickness as tape usage increases, which is time-consuming and labor-intensive. Furthermore, adjusting the paper thickness relies entirely on experience, resulting in inconsistent accuracy.

[0004] Therefore, it is necessary to design a pressure balancing device for adhesive tape to stabilize the pressure between the tape and the pressure roller when the tape usage changes, thereby stabilizing the tension and eliminating the need for adjustment from the start of use to the end of use. Utility Model Content

[0005] This application provides a pressure balancing device for adhesive tape in a YF71 automatic paper roll changer, which aims to solve the above-mentioned problems.

[0006] In one embodiment, a pressure balancing device for adhesive tape on a YF71 automatic paper roll changer is provided. This device is installed on the adhesive strip picking device of the YF71 automatic paper roll changer. The adhesive strip picking device includes a drive shaft, a tape reel, a pressure roller, and a tape application frame.

[0007] Positioning screws, positioning blocks, force adjustment springs, and fastening bolts;

[0008] The positioning screw mounts the device onto the pressure roller, and the pressure roller has a threaded hole for mounting the positioning screw;

[0009] One end of the positioning block has a through hole, and the positioning block is movably mounted on the positioning screw through the through hole. The other end of the positioning block contacts the edge of the adhesive tape reel, which is used to raise the position of the tape reel so that the tape reel does not press its own weight onto the pressure roller.

[0010] The force adjustment spring is installed on the positioning screw under the positioning block. A fastening bolt is installed on the positioning screw under the force adjustment spring. By adjusting the position of the fastening bolt on the positioning screw, the tension on the tape is adjusted, and the pressure on the entire tape is balanced.

[0011] In one embodiment, the positioning block is stepped, with a through hole on one step of the positioning block through which a positioning screw passes. The other step of the positioning block contacts the edge of the adhesive tape reel to raise the position of the tape reel.

[0012] In one embodiment, a through hole is formed on the higher step of the stepped positioning block, and the lower step of the stepped positioning block contacts the edge of the adhesive tape reel.

[0013] The beneficial effects of this application are:

[0014] By installing positioning screws on the pressure roller, and using positioning blocks, force adjustment springs, and fastening bolts to support the conveyor belt reel, the pressure between the conveyor belt reel and the pressure roller is stabilized when the conveyor belt usage changes. This stabilizes the tension on the conveyor belt, eliminating the need for frequent adjustments from the start of use to the end of use, reducing the workload of employees, and improving the stability of conveyor belt operation.

[0027] In some implementations, please refer to Figures 1 to 2 A pressure balancing device for adhesive tape in a YF71 automatic paper roll changer is provided. It is installed on the adhesive strip picking device of the YF71 automatic paper roll changer. The adhesive strip picking device includes a drive shaft 1, a tape reel 2, a pressure roller 3, and a tape sticking frame 4. When picking up the tape, the drive shaft 1 rotates, which drives the tape reel 2 to rotate. The tape is kept taut by the pressure roller 3. After a series of actions, the tape is finally stuck to the tape sticking frame 4.

[0028] A pressure balancing device for adhesive tape on a YF71 automatic paper roll changer includes:

[0029] Positioning screw 5, positioning block 6, force adjustment spring 7, and fastening bolt 8;

[0030] The positioning screw 5 mounts the device onto the pressure roller 3, and the pressure roller 3 has a threaded hole for mounting the positioning screw 5.

[0031] The positioning block 6 is stepped, with a through hole on the higher step of the positioning block 6 through which the positioning screw 5 passes. The lower step of the positioning block 6 contacts the edge of the adhesive tape reel 2, which is used to raise the position of the adhesive tape reel 2 so that the adhesive tape reel 2 does not press its own weight onto the pressure roller 3.

[0032] The force adjustment spring 7 is installed on the positioning screw 5 under the positioning block 6. The positioning screw 5 under the force adjustment spring 7 is equipped with a fastening bolt 8. By adjusting the position of the fastening bolt 8 on the positioning screw 5, the tension of the tape is adjusted, and the pressure on the whole tape reel is balanced.

[0033] In use, the adhesive tape pressure balancing device of the YF71 automatic paper roll changer is installed on the pressure roller 3 to replace the pressure roller 3 in receiving the weight of the tape roll. The tension of the force adjustment spring 7 is adjusted by tightening the bolt 8 to support the positioning block 6, thereby adjusting the tension of the tape and keeping the pressure within a reasonable range. This stabilizes the tension and ensures stable operation of the tape without frequent adjustments.
