Technical Field

[0001] This utility model relates to the field of paper slitting machine technology, specifically to an adjustable cutting distance paper slitting machine. Background Technology

[0002] A paper slitting machine is a mechanical device used to cut and rewind wide rolls of paper into rolls of different widths and diameters. It is mainly used in the paper processing and printing industries. In the paper processing industry, the paper slitting machine is a commonly used piece of equipment; its main function is to cut large sheets of paper into multiple smaller sheets according to the required specifications. The slitting blades, as the core component of the paper slitting machine, require precise adjustment of their spacing to meet the slitting needs of different paper sizes.

[0003] Existing paper slitting machines have many shortcomings in terms of adjusting the spacing between the slitting blades. Some paper slitting machines use a fixed blade mounting structure, where the spacing between the slitting blades is preset and cannot be adjusted. This means that the equipment can only slitting paper of a specific size. When it is necessary to slitting paper of other sizes, it is necessary to replace the slitting blade assembly of a different size or the entire equipment. Therefore, an adjustable cutting distance paper slitting machine is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a paper slitting machine with adjustable cutting distance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable paper slitting machine, including an operating table, a protective frame fixed on the top of the operating table, a plurality of slitting blades arranged inside the protective frame, and an adjustment component on one side of each slitting blade, the adjustment component being used to adjust the spacing between the slitting blades; A maintenance component is provided on one side of the adjustment component, and the maintenance component is used for disassembling and assembling the cutting blade; The adjustment assembly includes a first slide rod and a second slide rod. A plurality of sliding frames are slidably connected to the outside of the first slide rod. The slitting blade is slidably connected to the outside of the second slide rod. A bolt is threadedly connected to one side of the sliding frame. The maintenance component includes a baffle, with a third slide rod and a fourth slide rod fixedly inserted into one side of the baffle.

[0006] Preferably, the top of the operating table is fixed with two sets of support frames, each set having two support frames, and a rotating roller is rotatably connected between the two support frames. The rotating roller is used to guide the paper to be cut.

[0007] Preferably, the protective frame has a through hole at the top, and the through hole is located at the top of the sliding frame.

[0008] Preferably, one side of the sliding frame is fixed to one side of the slitting blade, and one end of the first slide rod and the second slide rod are fixed to one side of the protective frame.

[0009] Preferably, as described above, a connecting frame is fixed on one side of the protective frame, and a plurality of guide posts are fixed on one side of the connecting frame, with limit blocks sleeved on the outer side of the guide posts.

[0010] Preferably, the aforementioned limiting blocks are fixed to the outside of the baffle, and the baffle is connected to one side of the connecting frame by screws.

[0011] Preferably, the connecting frame has an insertion slot on one side, and the outer sides of the third and fourth slide rods are located inside the insertion slot.

[0012] Preferably, as described above, a protrusion is fixed at the center of one end of the third slide rod and the fourth slide rod, and a groove is provided at the center of one side of the first slide rod and the second slide rod. When the protrusion is inserted into the inside of the groove, the slitting blade is in the installed state; when the protrusion leaves the inside of the groove, the slitting blade is in the disassembled state.

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects: 1. When it is necessary to adjust the spacing of the sliding blades, simply loosen the bolts on the sliding frame to allow the sliding frame to slide freely on the first slide rod, thereby driving the sliding blades to move synchronously on the second slide rod. The operation is simple and convenient, and the spacing of the sliding blades can be adjusted quickly. After the sliding blades have moved to the desired position, tightening the bolts will firmly fix the sliding frame on the first slide rod, thereby ensuring the stability of the sliding blades and guaranteeing the quality of the sliding work. The through hole is located at the top of the sliding frame, providing ample operating space for the operator, making it convenient for the operator to move and fix the sliding frame from the top of the protective frame, thus improving the safety and convenience of the operation.

[0014] Second, by inserting the sliding frame and slitting blade along the first and second sliding rods during installation, and then using the limiting block on the outside of the baffle to fit onto the outside of the guide post and fix it with screws, the protrusions at one end of the third and fourth sliding rods are inserted into the grooves at the axis on one side of the first and second sliding rods.

[0020] Example Please see Figure 1-5This utility model provides a technical solution: an adjustable cutting distance paper slitting machine, including an operating table 1, a protective frame 7 fixed on the top of the operating table 1, a plurality of slitting blades 2 provided on the inner side of the protective frame 7, an adjustment component 5 provided on one side of the slitting blades 2, the adjustment component 5 being used to adjust the spacing of the slitting blades 2; a maintenance component 6 provided on one side of the adjustment component 5, the maintenance component 6 being used for disassembling and assembling the slitting blades 2. Two sets of support frames 3 are fixed to the top of the operating table 1. Each set contains two support frames 3, and a rotating roller 4 is rotatably connected between the two support frames 3. The rotating roller 4 is used to guide the paper to be cut. When the paper to be cut passes through the surface of the rotating roller 4, the rotation of the roller achieves the tensioning and directional conveying of the paper, ensuring that the paper remains flat and the conveying path is stable during the cutting process. An unwinding mechanism and a rewinding mechanism (not shown in the figure) are respectively provided at both ends of the operating table 1.

[0021] The adjustment assembly 5 includes a first slide rod 53 and a second slide rod 54. Both slide rods 53 and 54 are made of metal and are periodically lubricated. The spacing of the slitting blades 2 is also periodically checked, and adjustments are made promptly if an error is found. Several sliding brackets 52 are slidably connected to the outer side of the first slide rod 53. The slitting blades 2 are slidably connected to the outer side of the second slide rod 54. Bolts 51 are threaded onto one side of each sliding bracket 52. The sliding brackets 52 slide axially along the first slide rod 53, causing the slitting blades 2 to move synchronously along the second slide rod 54. By adjusting the relative positions of the multiple sliding brackets 52, the spacing between the slitting blades 2 is changed, achieving stepless adjustment of the cutting distance. The top of the protective frame 7 has a through hole 55, which is located on the top of the sliding frame 52 and directly above it. This provides operating space for the adjusting bolt 51, allowing tools to directly contact the head of the bolt 51 through the through hole 55, thus enabling unobstructed adjustment while the frame is protected. One side of the sliding frame 52 is fixed to one side of the slitting blade 2, and one end of the first slide rod 53 and the second slide rod 54 is fixed to one side of the protective frame 7. When the slitting blade 2 moves to the target position, the bolt 51 on one side of the sliding frame 52 is rotated so that its end abuts against the surface of the first slide rod 53. Through the friction between the bolt 51 and the first slide rod 53, the sliding frame 52 and the slitting blade 2 are locked in the set position, thus fixing the cutting distance.

[0022] The maintenance component 6 includes a baffle 65. A third slide rod 63 and a fourth slide rod 64 are fixedly inserted into one side of the baffle 65. Several guide posts 62 are fixed to one side of the connecting frame 61. Limiting blocks 66 are sleeved on the outside of the guide posts 62. The limiting blocks 66 are fixed to the outside of the baffle 65. The limiting blocks 66 sleeved on the outside of the guide posts 62 slide along the inner wall of the baffle 65 to limit the movement trajectory of the connecting frame 61. The baffle 65 is connected to one side of the connecting frame 61 by screws.

[0023] A connecting frame 61 is fixed on one side of the protective frame 7. An insertion slot is opened on one side of the connecting frame 61. The outer sides of the third slide rod 63 and the fourth slide rod 64 are located inside the insertion slot. Pushing the baffle 65 causes the protrusions 67 at the ends of the third slide rod 63 and the fourth slide rod 64 to be inserted into the grooves 68 on the sides of the first slide rod 53 and the second slide rod 54. The cutting blade 2 and the adjusting assembly 5 form a rigid connection, and the installation state is locked.

[0024] Both the third slide rod 63 and the fourth slide rod 64 have a protrusion 67 fixed at one end of their shafts. One end of the protrusion 67 has a rounded corner. The first slide rod 53 and the second slide rod 54 each have a groove 68 at one side of their shafts. When the protrusion 67 is inserted into the groove 68, the slitting blade 2 is in the installed state. When the protrusion 67 leaves the groove 68, the slitting blade 2 is in the disassembled state. Pulling the baffle 65 in the opposite direction causes the protrusion 67 at the ends of the third slide rod 63 and the fourth slide rod 64 to come out of the groove 68, and the connection between the slitting blade 2 and the adjusting assembly 5 is released. At this time, the slitting blade 2 can be taken out along the axial direction of the second slide rod 54 for maintenance or replacement.

[0025] Working principle: The operating table 1 serves as the supporting foundation for the entire slitting machine, and a protective frame 7 is fixed on its top. The protective frame 7 provides installation space and a certain degree of protection for the slitting blades 2, the adjustment components 5, and the maintenance components 6. Two sets of support frames 3 are fixed on the top of the operating table 1, with two supports in each set. A rotating roller 4 is rotatably connected between the two support frames 3. The paper to be slit passes around the rotating roller 4, which guides the paper to ensure that it enters the slitting area smoothly and accurately. When it is necessary to adjust the spacing of the slitting blades 2, first loosen the bolts 51 on the sliding frame 52. At this time, the sliding frame 52 can slide freely on the first slide rod 53. Since one side of the sliding frame 52 is fixed to one side of the slitting blade 2, pushing the sliding frame 52 to move on the first slide rod 53 will cause the slitting blade 2 to move synchronously on the second slide rod 54. After the slitting blade 2 moves to the desired position, tighten the bolts 51 to fix the sliding frame 52 on the first slide rod 53, thereby fixing the position of the slitting blade 2 and realizing the adjustment of the spacing of the slitting blades 2. The protective frame 7 has a through hole 55 at the top, and the through hole 55 is located at the top of the sliding frame 52. The through hole 55 provides operating space for the operator, making it convenient for the operator to move and fix the sliding frame 52 from the top of the protective frame 7.

[0026] Both the third slide bar 63 and the fourth slide bar 64 have protrusions 67 fixed at one end of their shafts. The first slide bar 53 and the second slide bar 54 each have grooves 68 on one side of their shafts. When the slitting blade 2 needs to be installed on the slitting machine, the sliding frame 52 and the slitting blade 2 are inserted along the first slide bar 53 and the second slide bar 54. Then, the baffle 65 is removed, so that the limiting block 66 on the outside of the baffle 65 is fitted onto the outside of the guide post 62. Then, the baffle 65 is fixed to one side of the connecting frame 61 using screws. At this point, the protrusions 67 are inserted into the grooves 68. The slitting blade 2 is now fixed in the appropriate position and in the installed state, ready for paper slitting. When maintenance or replacement of the slitting blade 2 is required, remove the screw on one side of the baffle 65, causing the baffle 65 to pull the third slide rod 63 and the fourth slide rod 64 out of the insertion slot, so that the protrusion 67 moves away from the inside of the groove 68. At this time, the connection between the slitting blade 2 and the maintenance component 6 and the adjustment component 5 is released, and the slitting blade 2 can be removed for maintenance or replacement by loosening the bolt 51.

[0027] In summary, when it is necessary to adjust the spacing of the slitting blades 2, simply loosen the bolts 51 on the sliding frame 52 to allow the sliding frame 52 to slide freely on the first slide bar 53, thereby driving the slitting blades 2 to move synchronously on the second slide bar 54. The operation is simple and convenient, and the spacing of the slitting blades 2 can be adjusted quickly. After the slitting blades 2 have moved to the desired position, tightening the bolts 51 will firmly fix the sliding frame 52 on the first slide bar 53, thereby ensuring the stability of the position of the slitting blades 2 and ensuring the quality of the slitting work. The through hole 55 is located at the top of the sliding frame 52, providing ample operating space for the operator, making it convenient for the operator to move and fix the sliding frame 52 from the top of the protective frame 7, thus improving the safety and convenience of the operation.

[0028] By inserting the sliding frame 52 and the slitting blade 2 along the first slide bar 53 and the second slide bar 54 during the installation of the slitting blade 2, and then using the limiting block 66 on the outside of the baffle 65 to fit onto the outside of the guide post 62 and fix it with screws, the protrusion 67 at one end of the third slide bar 63 and the fourth slide bar 64 is inserted into the groove 68 at the axis on one side of the first slide bar 53 and the second slide bar 54. This ensures the connection and fixation of the slitting blade 2 in multiple directions, greatly enhances the stability of the slitting blade 2 after installation, and effectively avoids the slitting blade 2 from shaking or shifting during the paper slitting process, thereby ensuring the slitting quality.

In particular, the features described in the various embodiments and / or claims of this utility model can be combined or combined in various ways without departing from the spirit and teachings of this utility model.
