Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper winding machines, and particularly relates to a paper feeding mechanism of a paper winding machine. Background Art
[0002] A paper winding machine is a set of equipment in the papermaking process of modern paper machines that winds the flat paper web into a tight and uniform paper roll, facilitating subsequent deep processing and enabling the entire paper machine to continuously produce with finished products coming off the line uninterruptedly. With the increasingly fierce competition in the paper industry, paper machines are developing towards high speed and wide width, and the requirements for paper winding machines are getting higher and higher. The roll changing mechanism of high-speed paper winding machines is of great significance to the development of the current paper machine industry. From raw material feeding, pulping, screening, refining, sizing, papermaking, pressing, to drying, a series of processes and consumptions are involved, and finally finished products are produced. Therefore, the last process must be stable and reliable. If there are problems with the paper winding machine, such as thick roll bottom, folding, and failed roll change, the entire production process will be in vain, resulting in a very large internal consumption during production, high production costs, and squeezing the profits of enterprises.
[0003] Currently, when changing the paper roll of a paper winding machine, a hoist hook is generally used, and the brake of the paper roll is hooked by the hook. This unreasonable operation method may cause major safety accidents to the hoist. On the other hand, it increases the probability of damage to components such as the hoist track, walking wheels, and crossbeam structure. On the other hand, accidents such as the wear of the paper roll cylinder shaft sleeve and shaft head due to the brake of the hook and the entry of worn metal powder into the bearing housing to damage the bearing may occur. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a paper feeding mechanism of a paper winding machine.

One end of the first spring abuts against the first support plate.
[0007] Preferably, a first adjusting nut is threadedly connected to the first movable rod.
[0008] Preferably, the buffer device includes buffer plates symmetrically arranged on both sides of the baffle. One end of the buffer plate is hinged to the track through a rotating shaft.

[0012] The beneficial effects of the present utility model are as follows: The present utility model adopts an inclined track, which is convenient for the secondary arm to freely move down after releasing the paper roll.

[0019] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
[0020] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.
[0021] Refer to Figures 1 to 3As shown in the figure, the structure of the present utility model is as follows: A paper feeding mechanism for a paper winder, including a frame 1, on which a paper winding cylinder 2 is rotatably arranged. At both ends of the paper winding cylinder 2, a primary arm 3 is movably arranged. On the primary arm 3, a paper winding roller 10 is rotatably arranged. On one side of the paper winding cylinder 2, a track 5 is inclined. Between the track 5 and the paper winding cylinder 2, a secondary arm 4 is movably arranged. On both sides of the track 5, a speed reduction device 6 is arranged. At the end of the track 5, a baffle 7 is arranged. On both sides of the baffle 7, a buffer device 8 and a braking device 9 are arranged. Specifically, the paper winding roller 10 is clamped by the primary arm 3, and the paper winding cylinder 2 assists in driving the paper roll of the paper winding roller 10. Subsequently, the primary arm 3 rotates, and the paper winding roller 10 is slowly transferred to the secondary arm 4. During operation, the paper winding roller 10 closely abuts against the rotating paper winding cylinder 2, and the paper made on the paper machine is wound into a tightly and evenly wound paper roll. The paper roll runs along with the paper machine, and the paper roll gradually becomes a large roll until the paper roll reaches the set diameter. The secondary arm 4 releases the paper winding roller 10, and the paper roll rolls down along the track 5 with a certain slope under the inertia of its own rotation. Subsequently, the speed reduction device 6 reduces the rolling speed of the paper winding roller 10 to avoid the rolling speed of the paper winding roller 10 being too fast. When the paper winding roller 10 rolls to the end of the track 5, the buffer device 8 slows down the impact force of the paper winding roller 10 hitting the baffle 7. Subsequently, the braking device 9 stops the paper winding roller 10, and then the paper roll is removed by a crane.
[0022] As Figure 2 shown, the speed reduction device 6 includes speed reduction plates 605 symmetrically arranged on both sides of the track 5. At the bottom of the speed reduction plate 605, a first movable rod 601 is hinged. At the end of the first movable rod 601, a first support plate 602 is inserted. The first support plate 602 is fixedly connected to the track 5. A first spring 603 is sleeved on the first movable rod 601. One end of the first spring 603 abuts against the first support plate 602. Specifically, because the track 5 is designed with a slope, the downward movement speed of the paper winding roller 10 will gradually increase. The speed reduction plate 605 forms a certain slope under the action of the first spring 603. When the paper winding roller 10 rolls onto the speed reduction plate 605, the rolling speed of the paper roll is thus reduced.
[0023] As Figure 2 shown, a first adjusting nut 604 is threadedly connected to the first movable rod 601. Specifically, the first adjusting nut 604 is used to adjust the elastic force of the first spring 603 so as to adapt to the speed reduction of paper rolls of different weights.
[0024] As Figure 3As shown in the figure, the buffer device 8 includes buffer plates 801 symmetrically arranged on both sides of the baffle. One end of the buffer plate 801 is hinged to the track 5 through a rotating shaft 802. The other end of the buffer plate 801 is hinged with a second movable rod 803. A second support plate 804 is inserted through the end of the second movable rod 803. The second support plate 804 is fixedly connected to the baffle 7. A second spring 805 is sleeved on the second movable rod 803. One end of the second spring 805 abuts against the second support plate 804. Specifically, when the paper roll 10 rolls to the end of the track 5, the buffer plate 801 abuts against the paper roll 10. Subsequently, the paper roll compresses the second spring 805 under the inertia of rolling, so that the paper roll gradually loses the kinetic energy of forward movement and slows down the impact force of the paper roll 10 hitting the baffle 7.
[0025] As Figure 3 shown in the figure, a second adjusting nut 806 is threadedly connected to the second movable rod 803. Specifically, the second adjusting nut 806 is used to adjust the elastic force of the second spring 805 to facilitate buffering of paper rolls of different weights.
[0026] As Figure 3 shown in the figure, the braking device 9 includes a crank arm 901 rotatably arranged on the rotating shaft. A brake 902 is provided at one end of the crank arm 901. The other end of the crank arm 901 is connected with a cylinder 903. A cylinder seat 904 movably connected with the cylinder 903 is provided on the baffle 7. Specifically, after the paper roll stops moving under the action of the buffer device 8, it is still rotating. At this time, the cylinder 903 drives the crank arm 901 to rotate, so that the brake 902 acts on the paper roll 10 to brake the paper roll and make it stop rotating.
[0027] As Figure 3 shown in the figure, a buffer arc slope 701 is provided on the baffle 7. Specifically, the buffer arc slope 701 is used to cooperate with the buffer device 8 to achieve double-action stopping.
[0028] During specific use, the paper roll 10 is clamped by the primary arm 3, and the paper roll of the paper roll 10 is assisted by the paper roll cylinder 2. Subsequently, the primary arm 3 rotates and slowly transfers the paper roll 10 to the secondary arm 4. During operation, the paper roll 10 closely abuts against the rotating paper roll cylinder 2, and the paper made on the paper machine is wound into a tight and uniform paper roll. The paper roll moves with the operation of the paper machine, and the paper roll gradually becomes a large roll. Until the paper roll reaches the set diameter, the secondary arm 4 releases the paper roll 10. The paper roll rolls along the track 5 with a certain slope under the inertia of its own rotation. Subsequently, the moving speed of the paper roll 10 is reduced by the speed reduction device 6 to avoid the moving speed of the paper roll 10 being too fast. When the paper roll 10 rolls to the end of the track 5, the impact force of the paper roll 10 hitting the baffle 7 is slowed down by the buffer device 8. Subsequently, the paper roll 10 is braked by the braking device 9, and then the paper roll is removed by the overhead crane.
[0029] The above further describes the present utility model by means of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
