Description

Technical Field

[0001] This utility model relates to the field of paper slitting, specifically to the moving parts of a paper slitting machine. Background Technology

[0002] A paper slitting machine cuts rolls of paper into different sizes, such as A4 and A3. The paper collection and paper alignment mechanisms of the slitting machine adjust the longitudinal position of the paper on the machine according to its specifications. For example, in collecting the slit paper, the longitudinal and lateral positions of the side baffles on the frame are adjusted according to the specifications of the slit paper to ensure neat stacking of the slit paper. The side baffles are installed on the crossbeam, and adjusting the longitudinal position of the crossbeam on the frame adjusts the longitudinal position of the side baffles.

[0003] The existing crossbeams are mounted on the left and right archways, using a gear and rack structure to achieve longitudinal movement. If the gears and racks mesh tightly, problems such as jamming and overload may occur during crossbeam movement. If the meshing is too loose, the crossbeam movement will be unstable and have poor accuracy. Therefore, the moving parts of the existing paper slitting machine need to be improved. Utility Model Content

[0004] In view of the technical problems existing in the background art, the technical problem solved by this utility model is to provide a moving part of a paper slitting machine that is stable and highly accurate.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the moving part of this paper slitting machine is characterized by including a fixed frame and a moving assembly.

[0006] The fixing frame includes a left fixing plate and a right fixing plate, and the surfaces of the left fixing plate and the right fixing plate are provided with racks, which are arranged longitudinally;

[0007] The moving component includes a gear seat and a crossbeam. Two gear seats are provided and are respectively installed at both ends of the crossbeam. The gear seats are equipped with gears that mesh with a rack. The gears are placed on the rack and the two gears rotate synchronously.

[0008] The gear seat, the left fixed plate, and the right fixed plate are equipped with adjustment components for adjusting the gap between the gear and the rack.

[0009] This invention adjusts the gap between the gear and the rack by adjusting the component, so that the meshing of the two is properly aligned, thus making the crossbeam move stably and accurately on the fixed frame.

[0010] Preferably, the left fixing plate and the right fixing plate are provided with guide grooves, and the guide grooves are arranged parallel to the rack.

[0011] The gear seat is provided with a sliding groove, which is obliquely arranged;

[0012] The adjustment assembly includes a slider, a roller that is rotatably mounted on the slider, the roller being matched with and placed in the guide groove, the slider being matched with and placed in the slide groove, and the slider being locked to the gear seat.

[0013] The height of the roller and the guide groove remains constant. The slide is set at an angle. When the slider moves in the slide, the height of the gear seat relative to the fixed frame will change slightly, thereby adjusting the gap between the gear and the rack.

[0014] Preferably, one end of the slide groove extends to the side face of the gear seat to form an opening; two sets of adjustment components are provided, with the slide grooves of the two sets of adjustment components symmetrically arranged on the gear seat. The opening facilitates the installation of the slider, and the symmetrical arrangement at the front and back makes adjustment easier.

[0015] Preferably, the slider and the gear seat are locked together by locking bolts.

[0016] Preferably, the guide groove is located on the inner sidewalls of the left and right fixed plates. This does not affect the appearance of the equipment and makes it safer to use. Attached Figure Description

[0022] The following description, in conjunction with the accompanying drawings, details the embodiments and working principles of this utility model. The moving parts of the paper slitting machine are used in the paper collecting mechanism, the web guiding mechanism, and the roll conveying mechanism, etc., of the paper slitting machine. In the figures, the moving parts are used in the paper collecting mechanism, which will be used as an example in the following explanation.

[0023] The moving parts of this paper slitting machine include a fixed frame and a moving assembly. The fixed frame includes a left fixed plate 3 and a right fixed plate, and racks 4 are provided on the surfaces of the left and right fixed plates, with the racks 4 arranged longitudinally. The moving assembly includes a gear seat 2 and a crossbeam 1. Two gear seats 2 are provided and are respectively installed at both ends of the crossbeam 1. Only the left fixed plate 3 and the left gear seat 2 are shown in the figure. The side baffle 12 of the paper collecting mechanism is installed on the crossbeam 1. The gear seat 2 is equipped with a gear 5 that meshes with the rack. The gear 5 is placed on the rack 4 and the two gears rotate synchronously. The two gears can be synchronously rotated by a gear shaft and driven by a motor. When the motor drives the gear to rotate, the gear 5 moves relative to the rack 4, that is, the gear seat 2 and the crossbeam 1 move longitudinally on the fixed frame, adjusting the longitudinal position of the side baffle 12 on the frame. The gear seat 2, the left fixed plate 3, and the right fixed plate are equipped with an adjustment component for adjusting the gap between the gear and the rack 4. By adjusting the gap between the gear and the rack 4 through the adjustment component, the meshing of the two is properly centered. In this way, the crossbeam 1 moves stably and accurately on the fixed frame, avoiding problems such as jamming, overload movement, and unstable movement in the prior art.

[0024] The left and right fixed plates are provided with guide grooves 6, which are parallel to the rack 4 and located on the inner sidewalls of the left and right fixed plates. This design does not affect the appearance of the equipment and enhances safety. (See Appendices 2 and 4). The gear seat 2 has a sliding groove 9, which is angled. The adjustment assembly includes a slider 8 with a rotatable roller 7. The roller 7 matches and is inserted into the guide groove 6. The slider 8 matches and is positioned within the sliding groove 9. The slider 8 is locked to the gear seat 2 using a locking bolt 10. To facilitate the installation and adjustment of the slider 8, one end of the sliding groove 9 extends to the side face of the gear seat 2, forming an opening 11. Two sets of adjustment assemblies are provided, with the sliding grooves 9 of the two sets symmetrically arranged on the gear seat 2.

[0025] The height of roller 7 relative to guide groove 6 remains constant. Slide 9 is angled, and as slider 8 moves within slide 9, the height of gear seat 2 relative to the fixed frame changes slightly, thus adjusting the gap between gear and rack 4. The two sets of adjustment components on the same gear seat 2 are adjusted accordingly. (See attached diagram.) Figure 4Specifically, when slider 8 moves to the right (upward) along the inclined groove 9, the gear seat 2 moves upward relative to the left fixed plate 3, increasing the gap between the gear and rack 4. Conversely, when slider 8 moves to the left (downward) along the groove 9, the gear seat 2 moves downward relative to the left fixed plate 3, decreasing the gap between the gear and rack 4. The other set of adjustment components makes corresponding adjustments, thus adjusting the gap between gear 5 and rack 4. After adjustment, the gap is locked by locking bolt 10. When the gap between gear and rack 4 is appropriate, the crossbeam 1 moves stably and accurately on the fixed frame.
