Description

Technical Field

[0001] This utility model relates to the field of paper printing technology, and in particular to a paper separation device for printing. Background Technology

[0002] The main components of a paper slitting machine have a relatively complex structure, and each component has a specific function during normal operation. The paper feeding system is the first step in the paper slitting machine, mainly used to feed the paper to be cut from the paper feeding device into the machine. It usually consists of a paper feeder, conveyor belt, drive device and tension control device, etc., to ensure that the paper enters the slitting area smoothly. The slitting blade assembly is the core part of the paper slitting machine, mainly used to cut the paper according to the set size. In existing paper slitting machines, the slitting blade assembly is usually fixed to the mounting frame by multiple sets of bolts. This design has certain drawbacks in many cases, especially during disassembly and maintenance, where it is often time-consuming and labor-intensive. Although the bolt fixing method of the slitting blade assembly can ensure the stability of the blade assembly, the disassembly work becomes extremely complicated when the equipment needs maintenance, blade replacement, or repair. Each set of bolts needs to be loosened one by one, and there are usually many bolts, often requiring the use of tools. The operation is both labor-intensive and time-consuming. Especially when the equipment needs to be repaired in a short time, this cumbersome disassembly process seriously delays production efficiency and is a problem that urgently needs to be solved. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a printing paper separation device. The device adopts a mounting base and a fixed plate fixed by a mounting rod, which makes the disassembly and installation process simpler. The operator only needs to pull the pull ring to drive the mounting rod. After the slider compresses the return spring, the slitting blade assembly can be pulled out from the fixed plate, which greatly reduces the time and labor intensity required for disassembly.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a printing paper separation device, including a paper separation device frame, a drive motor installed on the paper separation device frame, a slitting knife assembly installed on the paper separation device frame, the slitting knife assembly fixed on the paper separation device frame by a mounting component, a paper inlet connected to one side of the paper separation device frame through the drive motor, and a paper outlet connected to the other side of the paper separation device frame through the drive motor, with paper blanks connected to the paper inlet, the slitting knife assembly, and the paper outlet.

[0005] As a preferred technical solution of this utility model, the slitting blade assembly includes a slitting blade positioned above the middle position of the paper separation device frame, a rotating shaft disposed at both ends of the slitting blade, and a mounting base installed with the mounting assembly and rotatably connected to the rotating shaft.

[0006] As a preferred embodiment of this utility model, another set of drive motors is connected to the outer wall of the rotating shaft, and the mounting base is configured as a convex shape.

[0007] As a preferred technical solution of this utility model, the installation component includes a mounting frame disposed above the outer wall of the paper separation device frame, a fixed plate mounted on the upper end of the mounting frame, a groove opened in the fixed plate, a slider slidably connected in the groove, an installation rod connected to the slider and inserted into the fixed plate, a return spring wound around the outer wall of the installation rod, a pull ring fixed on the outer wall of the installation rod, and an installation groove opened in the mounting seat.

[0008] As a preferred embodiment of this utility model, two sets of fixing plates are symmetrically installed, and the distance between the two sets of fixing plates is set to be equal to the width of the mounting base.

[0009] As a preferred embodiment of this utility model, two sets of fixing plates are symmetrically installed, and the distance between the two sets of fixing plates is set to be equal to the width of the mounting base.

[0010] As a preferred embodiment of this utility model, the pull ring is shaped like a circular ring, and the outer wall of the pull ring is provided with anti-slip texture.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: Traditional slitting blade assemblies require multiple bolts to be fixed to the mounting bracket. Disassembly requires loosening each bolt individually, and since there are many bolts, tools are usually needed. This is not only cumbersome but also time-consuming, especially when the equipment needs emergency repairs or blade replacements, which seriously affects production efficiency. In contrast, this device uses a mounting rod to connect the mounting base and the fixed plate, making disassembly and installation much simpler. The operator only needs to pull the pull ring, which moves the mounting rod. After the slider compresses the return spring, the slitting blade assembly can be pulled out of the fixed plate, greatly reducing the time and labor intensity required for disassembly.

[0012] Because this design ensures stable installation of the tool assembly through the elastic action of the return spring, disassembly can be completed without the aid of tools, simply by pulling the pull ring. Especially in emergency situations, this quick disassembly and installation method can effectively improve maintenance efficiency and avoid production stoppages caused by untimely equipment maintenance.

[0013] The mounting base is designed with a convex shape to ensure that it can be accurately snapped between the fixing plates, avoiding the problem of misalignment during installation and enabling more precise initial positioning. During installation, the guide effect of the slide groove on the slider allows the mounting rod to be precisely aligned with the mounting groove, ensuring the stability of the entire slitting blade assembly. This avoids the loosening problem that may occur in traditional fixing methods and ensures the stability of the blade during long-term use. Attached Figure Description

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0017] Example: like Figure 1-4As shown, a printing paper separation device includes a paper separation device frame 1, a drive motor 2 installed on the paper separation device frame 1, a slitting knife assembly 3 installed on the paper separation device frame 1, the slitting knife assembly 3 being fixed to the paper separation device frame 1 by a mounting assembly 7, a paper inlet 4 connected to one side of the paper separation device frame 1 via the drive motor 2, and a paper outlet 5 connected to the other side of the paper separation device frame 1 via the drive motor 2. Paper pieces 6 are connected to the paper inlet 4, the slitting knife assembly 3, and the paper outlet 5. The slitting blade assembly 3 includes a slitting blade 31 positioned above the middle of the paper separating device frame 1, a rotating shaft 32 disposed at both ends of the slitting blade 31, and a mounting base 33 mounted to the mounting assembly 7 and rotatably connected to the rotating shaft 32. The mounting assembly 7 includes a mounting frame 71 disposed above the outer wall of the paper separation device frame 1, a fixing plate 72 mounted on the upper end of the mounting frame 71, a slide groove 73 formed in the fixing plate 72, a slider 74 slidably connected in the slide groove 73, a mounting rod 75 connected to the slider 74 and inserted into the fixing plate 72, a return spring 76 wound around the outer wall of the mounting rod 75, a pull ring 77 fixed on the outer wall of the mounting rod 75, and a mounting groove 78 formed in the mounting base 33; The mounting base 33 of the slitting blade assembly 3 is designed to be convex, which fits into two sets of symmetrically installed fixing plates 72. The distance between the two sets of fixing plates 72 is equal to the width of the mounting base 33, ensuring that the mounting base 33 can be accurately inserted into the fixing plates 72 in the horizontal direction when it is placed, avoiding left and right offset and achieving initial positioning. The operator pulls the ring 77 of the mounting component 7. The circular design, combined with the anti-slip texture on the outer wall, facilitates the application of force and prevents slippage. This causes the mounting rod 75, which is fixed to the ring 77, to move outward. At this time, the slider 74 connected to the mounting rod 75 slides synchronously along the groove 73 in the fixing plate 72. The return spring 76, which is wrapped around the outer wall of the mounting rod 75, is compressed, storing elastic potential energy. After the mounting base 33 is completely placed between the fixing plates 72, the ring 77 is released, and the return spring 76 releases its elastic force, pushing the slider 74 to slide in the opposite direction along the groove 73. This causes the mounting rod 75 to be inserted into the preset mounting slot 78 of the mounting base 33, completing the insertion and fixing. During this process, the guiding effect of the groove 73 on the slider 74 ensures that the mounting rod 75 is accurately aligned with the mounting slot 78, avoiding insertion deviation. The two sets of symmetrical mounting components 7 simultaneously fix the mounting base 33 from both sides, ensuring the installation stability of the slitting blade assembly 3. When the slitting blade 31 needs to be replaced or maintained, the disassembly operation and the installation are linked in reverse. The operator pulls the pull rings 77 on both sides again, which drives the slider 74 to compress the reset spring 76 through the mounting rod 75, so that the mounting rod 75 is pulled out from the mounting groove 78 of the mounting seat 33 and the positioning constraint is released.

[0018] Since the mounting base 33 and the fixing plate 72 are only fixed by the mounting rod 75 and the two are in clearance fit, after the constraint is released, the slitting blade assembly 3 can be directly removed from between the two fixing plates 72 in the horizontal direction to complete the disassembly.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the utility model as defined by the appended claims and their equivalents.
