Description

Technical Field

[0001] This application relates to the field of tissue paper production technology, and in particular to a flattening device for tissue paper production. Background Technology

[0002] In the tissue paper production line, large-area tissue rolls need to be pulled out for cutting, folding, and packaging. When pulling out tissues from large-area tissue rolls, the top of the tissue roll needs to be flattened to maintain the tension and flatness of the paper.

[0003] Existing tissue flattening devices use a flattening mechanism with an elastic band to press the tissues onto the top of the tissue tube. As the tissues are continuously pulled out of the tube, the elastic band remains taut at the top, providing adaptive pressing. However, different types of tissues have varying degrees of flexibility. If the elastic band remains taut at the same level, insufficient pressure may cause the tissues to wrinkle, while excessive pressure may cause them to break. Furthermore, it is difficult to adjust the pressure on different types of tissues, limiting its applicability. Utility Model Content

[0008] Optionally, the elastic flattening mechanism includes a cover plate hinged to one side of the frame, with two movable shafts movably disposed at the bottom of the cover plate, and an elastic band wound between the two movable shafts, the elastic band pressing against the top of the tissue roll.

[0009] Optionally, a drive motor is connected to the movable shaft near the frame, and the drive motor is located on the outer wall of the cover plate.

[0010] Optionally, the machine frame is provided in two parts, with a hinge shaft between the two parts, and one side of the cover plate is hinged to the hinge shaft.

[0011] Optionally, both outer walls of the frame are provided with support frames, and one side of the support frame is provided with a mounting seat. The top of the mounting seat is provided with a mounting groove, and a mounting shaft is installed between the two mounting grooves. A rotating roller is movably sleeved on the mounting shaft, and the rotating roller is used to wind the paper towel roll.

[0012] Optionally, the support frame is hinged to the outer wall of the frame so that the two ends of the support frame are located on both sides of the frame. A telescopic cylinder is hinged to the outer wall of the frame, and the telescopic end of the telescopic cylinder is hinged to the top of the support frame on the side away from the mounting base.

[0013] Optionally, the top of the mounting base has two rounded corners near the mounting slot.

[0029] Example

[0030] Reference Figures 1-4 This embodiment provides a paper towel production flattening device, including a frame 110. An elastic flattening mechanism 120 is hinged to one side of the frame 110. The elastic flattening mechanism 120 is used to press against the top of the paper towel tube 250. An extension frame 130 is connected to the side of the elastic flattening mechanism 120 away from the frame 110. Several counterweights 140 are detachably provided on the extension frame 130.

[0031] In this embodiment, when it is necessary to adjust the pressing force of the elastic flattening mechanism 120 on the tissue roll 250, a counterweight 140 of corresponding weight is configured on the extension frame 130 according to the flexibility of the current tissue, so that the elastic flattening mechanism 120 applies a corresponding amount of pressing force to the top of the tissue roll 250, thereby realizing the adjustable pressing degree for different types of tissues and improving the applicability.

[0032] As an optional implementation, a plurality of limiting blocks 150 are provided on the extension frame 130 along the length direction of the extension frame 130, and the limiting blocks 150 are used to limit the position of the counterweight block 140.

[0033] In this embodiment, by installing counterweights 140 at different positions of the limiting blocks 150, the lever principle can be used to create different lever forces in the extension frame 130, thereby forming a corresponding clamping force on the top of the tissue roll 250. Therefore, only one counterweight 140 needs to be set, and the counterweight 140 can be permanently set in the extension frame 130 without being removed. Therefore, each time adjustment is made, there is no need to add or remove the corresponding number of counterweights 140, reducing the risk of losing the counterweight 140, and the adjustment is convenient and quick.

[0034] It should be noted that the gap width between the limit blocks 150 can be matched with the thickness of the counterweight block 140.

[0035] As an optional implementation, the counterweight 140 has a locking groove 141 at its bottom, and the counterweight 140 is locked onto the extension frame 130 through the locking groove 141, which facilitates disassembly and installation.

[0036] As an optional implementation, the elastic flattening mechanism 120 includes a cover plate 121 hinged to one side of the frame 110. Two movable shafts 122 are movably arranged at the bottom of the cover plate 121. An elastic band 123 (which may be made of rubber) is wound between the two movable shafts 122. The elastic band 123 is pressed against the top of the tissue roll 250.

[0037] In this embodiment, as the tissue roll 250 is continuously pulled out, the diameter of the tissue roll 250 decreases. Under the weight of the cover plate 121, the cover plate 121 rotates around the hinged position on one side of the frame 110, so that the elastic band 123 can always press against the top of the tissue roll 250, thereby maintaining the pressing effect on the paper surface of the tissue roll 250. At the same time, the two movable shafts 122 can rotate, so under the friction between the paper surface of the tissue roll 250 and the elastic band 123, the elastic band 123 can rotate around the movable shaft 122 to reduce wear.

[0038] As an optional implementation, a drive motor 160 is connected to the movable shaft 122 on the side near the frame 110, and the drive motor 160 is located on the outer wall of the cover plate 121.

[0039] In this embodiment, the drive motor 160 (which may be a servo motor) can drive the movable shaft 122 to rotate, thereby pulling the elastic band 123 and another movable shaft 122 to rotate synchronously, thus coordinating with the tissue paper to be pulled out of the tissue paper tube 250. While ensuring the pressing effect on the tissue paper tube 250, the wear on the tissue paper tube 250 is further reduced, thereby improving the surface quality of the tissue paper tube 250.

[0040] As an optional implementation, there are two frames 110, and a hinge shaft 230 is provided between the two frames 110. One side of the cover plate 121 is hinged to the hinge shaft 230.

[0041] In this embodiment, when the tissue roll 250 needs to be installed, the cover plate 121 can be flipped directly from between the two frames 110 to the other side, thereby avoiding interference with the cover plate 121 during the installation process and facilitating the installation operation.

[0042] As an optional implementation, each of the two outer walls of the frame 110 is provided with a support frame 170. A mounting seat 180 is provided on the top of one side of the support frame 170. The top of the mounting seat 180 is provided with a mounting groove 181. A mounting shaft 190 is installed between the two mounting grooves 181. A rotating roller 210 is movably sleeved on the mounting shaft 190. The rotating roller 210 is used to wind the paper towel roll 250.

[0043] In this embodiment, when the tissue roll 250 needs to be installed, the tissue roll 250 has been pre-wound onto the rotating roller 210 with the mounting shaft 190 to form a paper roll assembly. Then, the mounting shafts 190 on both sides of the paper roll assembly are placed directly into the mounting groove 181 at the top of the mounting base 180. At this time, the tissue roll 250 is located between the two mounting bases 180, and the support frame 170 provides suspension support for the paper roll assembly. The installation is convenient and quick, and it is also convenient to quickly remove the mounting shaft 190 and the rotating roller 210 as a whole in the future.

[0044] As an optional implementation, the support frame 170 is hinged to the outer wall of the frame 110, such that the two ends of the support frame 170 are located on both sides of the frame 110. A telescopic cylinder 220 is hinged to the outer wall of the frame 110, and the telescopic end of the telescopic cylinder 220 is hinged to the top of the support frame 170 on the side away from the mounting base 180.

[0045] In this embodiment, since the tissue roll 250 needs to be suspended and has a certain height, in order to improve the ease of installation, the support frame 170 is hinged and rotated by the telescopic cylinder 220 to form a lever structure. When installing the tissue roll 250, the telescopic cylinder 220 first retracts to rotate the support frame 170 so that its installation end tilts downward. At this time, the mounting base 180 is lower in height so that the mounting shaft 190 in the paper roll assembly can be placed in the mounting groove 181. Then, the telescopic cylinder 220 extends to rotate the support frame 170, thereby raising the entire paper roll assembly to a certain height, so that the top of the tissue roll 250 is pressed against the elastic band 123.

[0046] As an alternative implementation, the top of the mounting base 180 has two rounded corners near the mounting groove 181, thereby forming an arc-shaped opening at the top of the mounting groove 181 to facilitate quick positioning and placement of the mounting shaft 190.

[0047] As an optional implementation, a number of guide rollers 240 located below the hinge shaft 230 are arranged between the two frames 110. The tissues pulled out by the tissue tube 250 pass around the number of guide rollers 240. The number of guide rollers 240 can be arranged at different heights and in different vertical planes, so as to pull the tissues out of the tissue tube 250 in a certain direction.

[0048] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
