Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-6 As shown, the present invention is a finished product slitting and sorting device for papermaking production.

[0021] Example 1 Please see Figure 1 , Figure 2 and Figure 4 In this invention, a technical solution is provided: a fixed bottom frame plate 1, an inner toothed conveyor belt 4 for conveying finished paper is provided on the inner side of the fixed bottom frame plate 1, a winding roller 603 is provided on the upper left side of the fixed bottom frame plate 1 for pre-processing and installation of finished paper, an outer frame 7 is installed on the upper end of the fixed bottom frame plate 1, a connecting frame 8 is provided on the left end of the outer frame 7, a leveling conveyor roller 806 for leveling finished paper is provided below the connecting frame 8, a movable connecting seat 13 for forward and backward horizontal movement is provided below the outer frame 7, and a first cutter 1303 and a second cutter 13012 are respectively provided below the movable connecting seat 13 for cutting finished paper by width and length.

[0022] A central support plate 101 is provided in the middle of the fixed bottom frame plate 1 to provide central support for the inner toothed conveyor belt 4. A guide plate 102 is provided on the right side of the central support plate 101 and is in close contact with the inner toothed conveyor belt 4 to guide and discharge the slit finished paper.

[0023] Furthermore, both the left and right sides of the inner toothed conveyor belt 4 are provided with drive gear shaft rollers 3 that are rotatably connected to the fixed bottom frame plate 1. Driven gear shaft rollers 5 are provided inside the drive gear shaft rollers 3. Both the drive gear shaft rollers 3 and the driven gear shaft rollers 5 are meshed with the inner toothed conveyor belt 4. The inner toothed conveyor belt 4 has reserved grooves 401 at equal intervals on its outer side, and the inner toothed conveyor belt 4 is fitted and connected to the middle support plate 101.

[0024] Furthermore, side baffles 604 are provided at both the front and rear ends of the winding roller 603 to center and limit the finished paper. The side baffles 604 are rotatably connected on the movable support frame 6.

[0025] Furthermore, the movable support frame 6 is snapped onto the upper left side of the fixed base frame plate 1, and the connection between the movable support frame 6 and the fixed base frame plate 1 is threaded with a first bolt 601.

[0026] Specifically, the take-up roller 603, which winds the finished paper, is first movably installed on the upper inner side of the movable support frame 6, and the movable support frame 6 is snapped onto the upper left side of the fixed base frame 1. The first bolt 601 passes through the lower end of the movable support frame 6 and is threadedly connected to the fixed base frame 1, thereby securing the connection between the movable support frame 6 and the fixed base frame 1. Side baffles 604 are provided at both the front and rear ends of the take-up roller 603, which can increase the loading capacity of the finished paper. When the second servo motor 602 is turned on to rotate the take-up roller 603, the finished paper wound on the outside of the take-up roller 603 can be loosened. When the finished paper is laid flat on the inner toothed conveyor belt 4, it can be stably conveyed.

[0027] Furthermore, both the drive gear shaft roller 3 and the driven gear shaft roller 5 are meshed with the internal tooth conveyor belt 4. When the first servo motor 2 is turned on to rotate the drive gear shaft roller 3, it can drive the meshed internal tooth conveyor belt 4 to rotate at a uniform speed. The middle support plate 101 connected to the fixed bottom frame plate 1 is provided in the middle of the internal tooth conveyor belt 4, which can support the middle of the internal tooth conveyor belt 4 and prevent the internal tooth conveyor belt 4 from deforming. The right surface of the internal tooth conveyor belt 4 is attached to the guide plate 102, which can guide and discharge the slit finished paper. A discharge conveyor belt or carton can be placed at the right end of the fixed bottom frame plate 1 so that the slit finished paper can be collected directly.

[0028] Example 2 This embodiment is derived based on Embodiment 1. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 5 In this invention, a technical solution is provided: both the front and rear ends of the flat conveyor roller 806 are movably connected to a movable connecting frame 803, and a damping spring 804 located above the mounting plate 802 is provided on the outer side of the upper end of the movable connecting frame 803. The movable connecting frame 803 forms an elastic telescopic movement on the mounting plate 802 through the damping spring 804.

[0029] Furthermore, a gear disk 807 is fixedly installed at the rear end of the leveling conveyor roller 806. An internal toothed belt 808 is meshed with the outer side of the gear disk 807. Side plates 809 are provided at both the front and rear ends of the gear disk 807 to center and limit the internal toothed belt 808.

[0030] Specifically, in embodiment one, when the finished paper is released from the take-up roller 603 onto the inner toothed conveyor belt 4, it passes under the leveling conveyor roller 806. When the first hydraulic telescopic rod 801 installed at the lower end of the connecting frame 8 is opened, the mounting plate 802 is driven to move downwards. When the leveling conveyor roller 806 contacts the upper surface of the finished paper, it can squeeze the finished paper. At this time, the third servo motor 805 is turned on to rotate the leveling conveyor roller 806, which can be used to assist in conveying the finished paper to improve efficiency. To improve the conveying efficiency of finished paper and prevent jamming, a gear disk 807 is fixedly installed at the rear end of the leveling conveyor roller 806. When the leveling conveyor roller 806 rotates, it drives the gear disk 807 to rotate synchronously. An internal toothed belt 808 is meshed with the outer side of the gear disk 807, which allows the gear disk 807 and its corresponding unit to rotate synchronously and in the same direction. Under the action of the side plate 809, the internal toothed belt 808 is centered and limited, preventing misalignment of the internal toothed belt 808 during rotation.

[0031] Furthermore, the leveling conveyor roller 806 is rotatably connected to the movable connecting frame 803, and the upper outer side of the movable connecting frame 803 is provided with damping springs 804 located at the four corners of the upper end of the mounting plate 802. This allows the movable connecting frame 803 to elastically extend and retract on the mounting plate 802 under the action of the damping springs 804, thereby enabling micro-adjustment of the leveling conveyor roller 806 up and down. This facilitates the extrusion and conveying of finished paper of different thicknesses and allows for the leveling of the finished paper under the extrusion pressure, preventing wrinkles from forming during the conveying process of the production machine.

[0032] Example 3 This embodiment is derived based on Embodiment 1. Please refer to [link / reference]. Figure 2 , Figure 3 and Figure 6 In this invention, a technical solution is provided: a reciprocating screw 12 is threadedly connected to the inner side of the upper end of the movable connecting seat 13, and the movable connecting seat 13 forms a front-to-back sliding connection within the support plate frame 10. A second hydraulic telescopic rod 9 connected to the outer frame 7 is provided at the upper end of the support plate frame 10.

[0033] Furthermore, a third hydraulic telescopic rod 1301 is installed on the lower left side of the movable connecting seat 13. A first support horizontal plate 1302 is provided at the lower end of the third hydraulic telescopic rod 1301. The first support horizontal plate 1302 is threadedly connected to the first cutter 1303 by a second bolt 1304. A limiting connecting rod 1306 that is rotatably connected to the support vertical rod 1305 is provided at the right end of the first support horizontal plate 1302. The right end of the limiting connecting rod 1306 is connected to the second support horizontal plate 13010. The upper end of the second support horizontal plate 13010 is provided with a movable vertical rod 1309. The upper end of the movable vertical rod 1309 is provided with a return spring 1308 located inside the sleeve 1307.

[0034] Furthermore, the inner sides of the first support plate 1302 and the second support plate 13010 are both provided with relief grooves that are connected to the limiting connecting rod 1306. The limiting connecting rod 1306 forms a fitting sliding structure in the first support plate 1302 and the second support plate 13010 respectively. The movable vertical rod 1309 forms an elastic telescopic movement within the sleeve 1307 via the return spring 1308.

[0035] Specifically, in conjunction with Embodiments 1 and 2, when the finished paper is conveyed to the upper middle part of the inner toothed conveyor belt 4, the second hydraulic telescopic rod 9 installed inside the outer frame 7 can be opened to adjust the overall height of the support plate frame 10. When the second cutter 13012 contacts the upper surface of the finished paper, the fourth servo motor 11 is turned to rotate the reciprocating screw 12, so that the movable connecting seat 13 threaded to the reciprocating screw 12 can move stably back and forth laterally within the support plate frame 10. At the same time, when the fifth servo motor 13011 is turned to rotate the second cutter 13012, the second cutter 13012 can be used to cut the finished paper by length so that the finished paper reaches the specified size range.

[0036] Furthermore, when it is necessary to cut the finished paper to the required width, the third hydraulic telescopic rod 1301 can be opened to drive the first support horizontal plate 1302 to move downward as a whole. Since the right end of the first support horizontal plate 1302 is provided with a limiting connecting rod 1306 connected to the second support horizontal plate 13010, when the first support horizontal plate 1302 moves downward, the limiting connecting rod 1306 can rotate around the lower end of the support vertical rod 1305 as the center point, so that the second support horizontal plate 13010 is at the limiting connecting rod 1306. The lever 6 moves upward, and the inner right side of the first support plate 1302 and the inner left side of the second support plate 13010 are both provided with clearance grooves, which can make the limiting connecting rod 1306 move stably. At this time, the second cutter 13012 is disengaged from the finished paper, and the first cutter 1303 moves downward and fits into the finished paper, so that the finished paper can be cut in width. Through the lever movement of the limiting connecting rod 1306, the finished paper can be switched back and forth between width cutting and length cutting.

[0037] The upper end of the second support plate 13010 is fixedly installed with a second support plate 13010 that moves elastically within the sleeve 1307 via a return spring 1308. This improves the stability of the lifting and lowering movement of the second support plate 13010 and allows for buffering when the second cutter 13012 cuts the finished paper by length, thus avoiding damage to the inner toothed conveyor belt 4. In conjunction with the reserved grooves 401 equidistantly opened on the inner side of the outer end of the inner toothed conveyor belt 4, the size can be adjusted when cutting the finished paper by width.

[0038] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
