Description

Technical Field

[0001] The utility model relates to the technical field of paper processing, in particular to a guiding device for a hob machine. Background Technique

[0002] Paper is the general term for paper, and paper is generally divided into: letterpress printing paper, newsprint, offset printing paper, coated paper, book cover paper, dictionary paper, copy paper, board paper, etc.

[0003] In the process of paper production and processing, a hob slitter is used to slit the paper coil into the required width, so as to carry out the next production. When the width of the slit paper needs to be adjusted, the blade needs to be adjusted left and right on the rotating shaft to change the distance between the blades on each rotating shaft, so as to achieve the purpose of adjusting the slitting width. However, the current fixed structure between the blade and the rotating shaft is relatively complex, which makes it time-consuming and laborious for the staff to adjust the blade left and right and delays the processing efficiency. Therefore, it is necessary to design a guiding device for a hob machine to solve this problem. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] Many specific details are set forth in the following description in order to provide a thorough understanding of the present utility model. However, the present utility model may be practiced in other ways than those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed herein.

[0023] Please refer to Figures 1-5, the present utility model provides a guiding device for a hob machine: including a bracket 1, a horizontally arranged adjusting plate 2 is arranged directly above the bracket 1, two vertically arranged supporting plates 3 which are symmetric left and right are fixedly connected to the bottom of the adjusting plate 2, a rotating shaft 4 in the left-right axial direction is rotatably arranged between the two supporting plates 3, and a plurality of blades 41 distributed at equal intervals are sleeved on the rotating shaft 4. On both sides of each blade 41, there is an annular clamping block 5 sleeved on the rotating shaft 4 and used for clamping the blade 41. The annular clamping block 5 is provided with a fixing member capable of detachably fixing it on the rotating shaft 4. Through such a design, under the action of the fixing member, the fixing of the annular clamping block 5 on the rotating shaft 4 can be released. At this time, each annular clamping block 5 and the blade 41 can be slid on the rotating shaft 4, so that the distance between every two blades 41 can meet the width to be slit. Then, each blade 41 is clamped by the corresponding two annular clamping blocks 5, and the position of the annular clamping block 5 is fixed by the fixing member, so that the change of the slit width of the hob machine can be realized. And this design can conveniently and quickly adjust the blade 41 in the left-right direction, and quickly realize the change of the horizontal slit guiding of the blade 41, so as to reduce the working hours delayed when changing the paper slit width.

[0024] Specifically, in order to detachably fix the annular clamping block 5 on the rotating shaft 4, in some embodiments, it is proposed that a threaded hole 6 is opened on the circumferential surface of the annular clamping block 5, and a limit bolt 7 whose one side abuts against the surface of the rotating shaft 4 is inserted into the threaded hole 6 through threads. By rotating the limit bolt 7, the detachable fixing of the annular clamping block 5 on the rotating shaft 4 can be realized.

[0025] Please refer to Figure 5 , a first positioning hole 8 is opened on the blade 41, a second positioning hole 9 located on the same central axis as the first positioning hole 8 is opened on one of the annular clamping blocks 5, and a positioning rod 10 inserted into the first positioning hole 8 and the second positioning hole 9 is fixedly connected to one side of the other annular clamping block 5. So that after the two annular clamping blocks 5 are fixed on the rotating shaft 4, when the rotating shaft 4 rotates, the two annular clamping blocks 5 will rotate synchronously, and the blade 41 will be driven to rotate synchronously through the positioning rod 10 to achieve the slitting effect. Compared with only relying on the clamping force to drive the blade 41 to rotate, the problem of the blade 41 rotating and slipping can be avoided.

[0026] In some embodiments, two symmetrically arranged and inverted U-shaped fixing frames 11 are fixedly connected to the top of the bracket 1, a horizontally arranged mounting plate 12 is fixedly connected to the tops of the two fixing frames 11, and an oil cylinder 13 with a piston rod facing downwards is inserted into the mounting plate 12. The adjusting plate 2 is fixedly connected to the end of the piston rod of the oil cylinder 13. When the piston rod of the oil cylinder 13 expands and contracts, it can drive the adjusting plate 2 to lift synchronously, so that the height position of the blade 41 can be adjusted. Such a design will be more reasonable.

[0027] Please refer to Figure 2 and Figure 4 , the two support plates 3 are respectively a fixed plate 31 and a movable plate 32. The fixed plate 31 is fixedly connected to one side of the bottom of the adjusting plate 2. One side of the rotating shaft 4 is rotatably connected to the fixed plate 31 through a bearing, and a motor 14 is fixedly installed on one side of the fixed plate 31. One side of the rotating shaft 4 penetrates through the fixed plate 31 and is fixed to the end of the output shaft of the motor 14. Under the action of the motor 14, the rotating shaft 4 and the blade 41 can be driven to rotate. A chute penetrating through it along its length direction is opened on one side of the bottom of the adjusting plate 2 away from the fixed plate 31. The top of the movable plate 32 is snap-fitted and slidably inserted into the chute. A cylindrical groove 15 is opened at the bottom of one side of the movable plate 32. A sleeve 16 is rotatably inserted into the cylindrical groove 15 through a bearing. A limiting block 18 is provided on the inner wall of the sleeve 16. One side of the rotating shaft 4 away from the fixed plate 31 is inserted into the sleeve 16, and a limiting groove 17 is opened on one side of the surface of the rotating shaft 4. The limiting block 18 is inserted into the limiting groove 17. A moving component for moving the movable plate 32 left and right is provided on the adjusting plate 2. In this way, through the action of the moving component, the movable plate 32 can be moved away from the rotating shaft 4, so that one side of the rotating shaft 4 can be separated from the sleeve 16. At this time, the staff can take out or add the redundant blades 41 and the annular clamping blocks 5 on the rotating shaft 4 to change the number of the blades 41 and the annular clamping blocks 5 according to the slitting requirements. Such a design will be more reasonable.

[0028] In order to enable the movable plate 32 to move left and right, in some embodiments, the moving component includes two fixing blocks 19 fixedly connected to the top of the adjusting plate 2 and symmetrically arranged left and right. A threaded rod 20 passing through the movable plate 32 through threads is rotatably connected between the two fixing blocks 19. One side of the threaded rod 20 penetrates through one of the fixing blocks 19 and is fixedly connected to a handwheel 21. The staff can hold the handwheel 21 with their hand and rotate it, so that the threaded rod 20 can be rotated. The threaded rod 20 will drive the movable plate 32 to move left and right along the chute through the cooperation of the threads.

[0029] At the idle place of this device, all electrical components and their matching drivers are arranged, and through the personnel in this field, all the above-mentioned driving components, which refer to power elements, electrical components and the adapted power supply, are connected through wires. For the specific connection means, reference should be made to the above description for the electrical connection completed according to the sequential working order among the electrical components.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
