Description

Technical Field

[0001] The utility model relates to the technical field of paper winding machines, and particularly refers to a shearing structure with a pressing wheel. Background Art

[0002] A paper winding machine drives the paper to be evenly wound by relying on the self-weight of the paper winding roller and the frictional force during the rotation of the cold cylinder, so that the paper is more uniform, and thus the needs of different papers can be met. At the same time, after the paper is wound, that is, after the paper has been wound on the paper tube, it is also necessary to cut the paper, and then move the paper tube with the paper to the next position. However, the existing structure only limits the top of the paper tube with the paper, and after the knife cuts the paper, there is no structure to limit the cut part, resulting in the end of the cut paper being warped. If the warping arc is relatively large, then in the subsequent process, the paper on the paper tube may become loose. Summary of the Utility Model

[0029] The following further describes in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0030] As Figures 1 - 6 shown, a shearing structure with a pressing wheel includes a mounting bracket 1, and a knife 2 that is movable and used for shearing paper is provided on the mounting bracket 1, and a pressing shaft 3 that is movable and limits the top of a paper tube with paper. At the same time, at least one movable pressing wheel 4 is provided on the mounting bracket 1, and the pressing wheel 4 is located between the pressing shaft 3 and the knife 2, and the pressing wheel 4 contacts the side of the paper to be sheared so as to make it fit with the paper on the paper tube.

[0031] Therefore, in the actual use process, through the setting of the pressing wheel 4, the paper to be sheared is limited, and the sheared part is made to fit with the paper on the paper tube, thereby avoiding the situation that the end of the sheared paper will warp. At the same time, if the paper is not completely sheared and there is still some connection, the pressing wheel 4 can also play a role in further shearing.

[0032] The pressing wheel 4 can be a single long strip shaft or multiple short strip shafts. When it is multiple short strip shafts, that is, as Figures 4 - 6 shown, the structure of the pressing wheel 4 is: First, the pressing wheel 4 includes a connecting portion 42 and mounting shafts 43 located on both sides of the connecting portion 42, and wheels are sleeved on the mounting shafts 43.

[0033] At the same time, a first drive source 61 is provided on the mounting bracket 1, and the first drive source 61 is connected to the pressing wheel 4 and used to drive the up and down movement of the pressing wheel 4. The first drive source 61 is a cylinder, and there are two of them. Moreover, in order to prevent the movement from tilting, a guide rod is also provided.

[0034] Moreover, the structure between the pressing wheel 4 and the mounting bracket 1 is as follows: Firstly, several pressing wheels 4 are arranged on the mounting bracket 1, and each pressing wheel 4 is connected with a first connecting plate 51. The several first connecting plates 51 are connected through a second connecting plate 52, and the first connecting plate 51 is located between the side of the pressing wheel 4 away from the pressing shaft 3 and the side of the second connecting plate 52 close to the pressing shaft 3.

[0035] Therefore, during actual use, since the first connecting plate 51 is located between the side of the pressing wheel 4 away from the pressing shaft 3 and the side of the second connecting plate 52 close to the pressing shaft 3, when pressure is applied to the pressing wheel 4 to move it outward, at this time, due to the end of the first connecting plate 51 connected to the second connecting plate 52 being restricted by the second connecting plate 52, the possibility of the pressing wheel 4 moving outward is reduced.

[0036] Secondly, the mounting structure of the first connecting plate 51 is as follows: Firstly, a first slot 41 is formed on the side of the pressing wheel 4 away from the pressing shaft 3, and one end of the first connecting plate 51 is located in the first slot 41 and is connected to the pressing wheel 4 through a fastener. The fastener is a screw.

[0037] Moreover, a second slot 521 is formed on the side of the second connecting plate 52 close to the pressing shaft 3, and one end of the first connecting plate 51 is located in the second slot 521 and is connected to the second connecting plate 52 through a fastener. The fastener is a screw.

[0038] Therefore, during actual use, both ends of the first connecting plate 51 are located in the slots and are fixed through fasteners.

[0039] As Figures 1 - 4 shown, a second driving source 62 and a movable moving bracket 7 are arranged on the mounting bracket 1. The moving bracket 7 includes two first side plates 71, and a first mounting plate 72 and a second mounting plate 73 located between the two first side plates 71. The first side plate 71 is connected to the second driving source 62. A movable cutter 2 and a pressing wheel 4 are arranged on the first mounting plate 72, and a movable pressing shaft 3 is arranged on the second mounting plate 73.

[0040] The second driving source 62 is a cylinder and there are two of them. Therefore, during actual use, in addition to being able to move separately, the cutter 2, the pressing shaft 3, and the pressing wheel 4 can also move synchronously, that is, realized through the second driving source 62. The guiding structure during the movement of the moving bracket 7 is as follows: Firstly, a slider is arranged on the moving bracket 7, a slide rail is arranged on the second side plate 11 of the mounting bracket 1, and a second placement groove 111 for placing the slide rail is correspondingly formed on the second side plate 11.

[0041] At the same time, the first mounting plate 72 is movable and is provided with an assembly plate 721, the second mounting plate 73 is provided with an assembly plate 731, and a screw rod 74 passes through the assembly plate 731 and is threadedly connected to the assembly plate 721.

[0042] Therefore, during actual use, by rotating the screw rod 74, the first assembly plate 721 is driven to move back and forth, thereby adjusting the position of the first mounting plate 72, that is, adjusting the positions of the knife 2 and the pressure wheel 4, so as to adapt to paper cylinders of different sizes with paper.

[0043] Moreover, the guiding structure during the movement of the first mounting plate 72 is as follows: First, a slider is provided on the second mounting plate 73, a slide rail is provided on the first mounting plate 72, and the second mounting plate 73 is correspondingly provided with a first placement groove 732 for placing the slide rail. Second, in order to facilitate the rotation of the screw rod 74, a knob 75 is provided at the end of the screw rod 74, and the knob 75 rotates synchronously with the screw rod 74, that is, by rotating the knob 75, the rotation of the screw rod 74 is driven.

[0044] Second, the movement of the knife 2 can be up and down movement, that is, vertical shearing, or left and right movement, that is, horizontal scoring. When it is up and down movement, first, a third driving source 63 is provided on the first mounting plate 72, and the third driving source 63 is connected to the knife 2 and used to drive the up and down movement of the knife 2. The third driving source 63 is a cylinder, and there are two of them. Moreover, in order to prevent the movement from tilting, a guiding rod is also provided.

[0045] When it is left and right movement, first, a fourth driving source is provided on the mounting frame 1, the fourth driving source is connected with a transmission belt group, and the transmission belt group includes a conveyor belt and two conveyor wheels located inside the conveyor belt. One of the conveyor wheels is connected to the fourth driving source and rotates under the drive of the fourth driving source. Moreover, the knife 2 is connected to the conveyor belt, and the conveyor belt moves under the rotation of the conveyor wheels and drives the left and right movement of the knife 2.

[0046] The fourth driving source is a motor. When the fourth driving source drives the conveyor wheels to rotate, the conveyor belt is driven to move, thereby driving the left and right movement of the moving knife 2. At the same time, the guiding structure for the left and right movement of the knife 2 is also a slider and a slide rail. The knife 2 is connected to the conveyor belt through an assembly plate, and a sixth driving source is provided between the assembly plate and the knife 2. The sixth driving source is a cylinder to drive the up and down movement of the knife 2, and thus the position can be adjusted.

[0047] Moreover, in order to make the scoring effect better, that is, the knife 2 is connected with a seventh driving source, and the seventh driving source is a motor and drives the rotation of the knife 2.

[0048] At the same time, the movement structure of the pressure shaft 3 is as follows: First, a fifth driving source 65 is provided on the second mounting plate 73, and the fifth driving source 65 is connected to the pressure shaft 3 and used to drive the up and down movement of the pressure shaft 3. The fifth driving source 65 is a cylinder, and there are two of them. Moreover, in order to prevent the movement from tilting, a guiding rod is also provided.

[0049] The foregoing has shown and described the basic principles, main features and advantages of the present utility model.
