[0001] The utility model relates to the field of paper product production equipment, in particular to a waste paper shredder for paper product production. Background Art

[0002] Waste paper refers to recyclable resources that are discarded after use in production and life, including various high-grade paper, yellow cardboard, waste cardboard boxes, trimming paper, baling paper, corporate paper, engineering paper, books, newspapers, etc. In the process of waste paper recycling, a waste paper shredder is needed to shred the larger waste paper, which is convenient for use in subsequent processes.

[0003] The existing waste paper shredder is only provided with two shredding shafts, and the waste paper is only shredded once and cannot be fully shredded. There are also larger waste paper fragments in the waste paper fragments, which affects the subsequent use of the waste paper fragments. Utility Model Content

[0004] In order to overcome the disadvantage that the existing waste paper shredders cannot fully shred waste paper, thus affecting the subsequent use of waste paper fragments, the utility model provides a waste paper shredder for paper product production which can fully shred waste paper.

[0005] A waste paper shredder for paper product production includes a base, a mounting plate, a shredding cylinder, a first shredding shaft, a first gear and a first motor. The mounting plate is symmetrically fixed to the front and rear sides of the right side of the base, and the shredding cylinder is fixed between the two mounting plates. The lower part of the shredding cylinder is a cylinder, a feed inlet is provided on the right side of the upper part of the shredding cylinder, and a discharge outlet is provided on the left side of the lower part of the shredding cylinder. The first shredding shaft is symmetrically rotatably connected between the middle and upper parts of the front and rear panels of the shredding cylinder, the rear ends of the two first shredding shafts are fixed to the first gears, and the two first gears are meshed with each other. The first motor is fixed to the right side of the middle and upper part of the outer wall of the front panel of the shredding cylinder, and the output shaft of the first motor is fixed to the front end of the first shredding shaft located on the right side.

[0006] Further description, it also includes a second shredding shaft, a second gear, a pulley assembly, a rotating shaft, a rotating fan blade, a second motor and a screen. Four second shredding shafts are rotatably connected in parallel between the middle and lower parts of the front and rear panels of the shredding cylinder. The front ends of the four second shredding shafts are fixedly connected to the second gear. The first motor is driven by the second shredding shaft located on the far right through the pulley assembly. A rotating shaft is rotatably connected between the lower parts of the front and rear panels of the shredding cylinder. The rotating fan blade is fixedly connected to the middle part of the rotating shaft. The second motor is fixedly connected to the lower part of the outer wall of the front panel of the shredding cylinder. The output shaft of the second motor is fixedly connected to the front end of the rotating shaft. A screen is arranged at the bottom of the shredding cylinder.

[0007] Further explanation: It also includes a mounting frame, a material transport hopper and a handle. Mounting frames are symmetrically and fixedly connected to the front and rear of the left side of the base. A material transport hopper is slidably connected between the right parts of the two mounting frames. A handle is fixedly connected to the outer side wall of the panel of the material transport hopper away from the connection with the mounting frame. A square opening is provided in the upper left part of the shredding cylinder.

[0008] Further explanation: It also includes a mounting frame and a collection box. The mounting frame is fixedly connected to the right side of the middle part of the base.

[0012] Adopting the above scheme, the beneficial effects achieved by the present utility model are as follows:

[0013] 1. The second shredding shafts with a relatively small distance between each other are provided to perform secondary shredding on the waste paper fragments. The waste paper fragments that are still adhered together are pushed out of the shredding cylinder by the rotating fan blades for re-shredding treatment. In this way, the waste paper is fully shredded, facilitating subsequent use.

[0014] 2. The waste paper fragments pushed out from the discharge port fall into the material transport hopper. In this way, it can prevent the waste paper fragments from accumulating on the ground and being scattered by the wind, affecting the surrounding environment. And it is more labor-saving to lift the material transport cylinder upward along the mounting frame. The return spring, buffer plate and rubber sleeve are optimally arranged. The material transport hopper contacts the buffer plate downward, and the buffer plays a buffering role by squeezing the return spring. In this way, it can prevent the material transport hopper from colliding with the base and being damaged due to the user prematurely releasing the material transport hopper. The rubber sleeve can prevent the user's hand from being damaged by friction with the handle.

[0015] 3. The collection box collects the waste paper fragments falling from the screen, preventing the waste paper fragments from piling up and being scattered by the wind, affecting the surrounding environment.

[0016] 4. The diversion block distributes the waste paper fragments falling between the two first shredding shafts evenly between the second shredding shafts. In this way, it can prevent the waste paper fragments from accumulating between the two second shredding shafts in the middle. Description of the Drawings

[0023] Embodiment 1

[0024] A waste paper shredder for paper product production, as Figures 1-4 shown, includes a base 1, a mounting plate 2, a shredding cylinder 3, a first shredding shaft 6, a first gear 7 and a first motor 8. The mounting plates 2 are symmetrically welded to the front and rear sides of the right side of the base 1. The shredding cylinder 3 is connected between the two mounting plates 2 by bolts. The lower part of the shredding cylinder 3 is a cylinder. The upper right side of the upper part of the shredding cylinder 3 is provided with a feeding port 4. The lower left side of the lower part of the shredding cylinder 3 is provided with a discharging port 5. The upper middle parts of the front and rear two panels of the shredding cylinder 3 are symmetrically and rotatably connected with the first shredding shafts 6 left and right. The rear ends of the two first shredding shafts 6 are both welded with the first gears 7, and the two first gears 7 mesh with each other. The upper middle right side of the outer side wall of the front panel of the shredding cylinder 3 is connected with the first motor 8 by bolts. The output shaft of the first motor 8 is connected with the front end of the first shredding shaft 6 on the right side through a coupling.

[0025] As Figure 1 , Figure 2 and Figure 3As shown, it also includes a second shredding shaft 9, a second gear 10, a pulley assembly 11, a rotating shaft 12, a rotating blade 13, a second motor 14 and a screen 15. Four second shredding shafts 9 are rotatably connected in parallel between the middle and lower parts of the front and rear panels of the shredding cylinder 3. The front ends of the four second shredding shafts 9 are welded with second gears 10. The first motor 8 is driven by the second shredding shaft 9 located on the far right through the pulley assembly 11. The rotating shaft 12 is rotatably connected between the lower parts of the front and rear panels of the shredding cylinder 3. The rotating blade 13 is welded to the middle part of the rotating shaft 12. The lower part of the outer side wall of the front panel of the shredding cylinder 3 is connected to the second motor 14 by bolts. The output shaft of the second motor 14 is connected to the front end of the rotating shaft 12 by a coupling. The screen 15 is clamped at the bottom of the shredding cylinder 3.

[0026] The user starts the first motor 8, and the first motor 8 drives the first shredding shaft 6 on the right to rotate counterclockwise, thereby driving the first shredding shaft 6 on the left to rotate clockwise through the first gear 7. At the same time, the first motor 8 drives the second shredding shaft 9 on the far right to rotate counterclockwise through the pulley assembly 11, thereby driving the second shredding shafts 9 on the right and the far left in the middle to rotate clockwise through the second gear 10 in turn, and the second shredding shaft 9 on the left in the middle to rotate counterclockwise. The user puts the waste paper to be processed into the shredding cylinder 3 through the feed port 4 and it falls on the two first shredding shafts 6. The two first shredding shafts 6 squeeze the waste paper between them and drop it downward onto the second shredding shaft 9, thereby completing the preliminary shredding. The waste paper passes through the small gap between the two. After passing through the second shredding shaft 9, the waste paper is shredded into smaller pieces, which fall onto the rotating fan blades 13. The worker then starts the second motor 14, which drives the rotating fan blades 13 to rotate clockwise through the rotating shaft 12. The rotating fan blades 13 push the waste paper fragments through the screen 15. Under the action of gravity, the smaller waste paper fragments fall out of the shredding cylinder 3 from the screen 15, and the waste paper that is still stuck together after the second shredding is pushed out of the shredding cylinder 3 from the discharge port 5 by the rotating fan blades 13. The worker collects the waste paper and pours it into the shredding cylinder 3 from the feed port 4 for further shredding. Finally, the waste paper is ground into smaller pieces and falls off the screen 15. The worker collects the pieces for later use, thus completing the full shredding process of the waste paper.

[0027] Example 2

[0028] On the basis of Example 1, Figure 1 and Figure 2 As shown, it also includes a mounting frame 16, a material transport hopper 17 and a handle 18. The mounting frame 16 is symmetrically connected to the left side of the base 1 by bolts, and the material transport hopper 17 is slidably connected between the right parts of the two mounting frames 16. The handle 18 is welded on the outer wall of the panel of the material transport hopper 17 away from the connection with the mounting frame 16.

[0029] like Figure 1 andFigure 2 As shown, it further includes a rubber sleeve 22, and the middle part of the handle 18 is sleeved with the rubber sleeve 22.

[0030] The rotating fan blade 13 pushes out the waste paper fragments stuck together from the discharge port 5 out of the shredding cylinder 3 and into the material conveying hopper 17. When a sufficient amount of waste paper fragments are collected in the material conveying hopper 17, adding waste paper into the shredding cylinder 3 is stopped. When no more waste paper fragments are pushed out from the discharge port 5, the worker lifts the material conveying hopper 17 upward along the mounting frame 16. Since the outer periphery of the handle 18 is sleeved with the rubber sleeve 22, it can prevent the user's hand from being damaged by friction with the handle 18. After lifting the material conveying hopper 17 to the highest position, it is slid to the right and turned upward so that the material conveying hopper 17 fits against the upper right side of the shredding cylinder 3. At this time, the waste paper fragments in the material conveying hopper 17 fall into the shredding cylinder 3 through the square opening 181.

[0031] As Figure 1 、 Figure 2 and Figure 4 As shown, it further includes a mounting frame 182 and a collection frame 183. The mounting frame 182 is welded to the right side of the middle part of the base 1. Two collection frames 183 are slidably connected up and down in the mounting frame 182, and the upper collection frame 183 has a larger capacity than the lower collection frame 183.

[0032] The waste paper fragments fall downward through the screen 15 into the upper collection frame 183. When a sufficient amount of waste paper fragments are collected in the upper collection frame 183, the user pulls it out of the mounting frame 182 and quickly pours the waste paper fragments into the collection container, and then resets the collection frame 183. The lower collection frame 183 plays a transitional role and does not affect the continuous falling of the waste paper fragments from the screen 15.

[0033] As Figure 3 As shown, it further includes a diversion block 19, and the diversion block 19 is welded between the middle parts of the front and rear two panels of the shredding cylinder 3.

[0034] After the waste paper is shredded by the first shredding shaft 6, it falls downward, and the diversion block 19 distributes the waste paper falling downward evenly to the two second shredding shafts 9 on the same side.

[0035] As Figure 1 As shown, it further includes a return spring 20 and a buffer plate 21. The return springs 20 are symmetrically welded to the front and rear of the middle part on the left side of the base 1, and the buffer plate 21 is welded between the sides of the two return springs 20 far away from the connection with the base 1.

[0036] After the user pours the waste paper fragments in the material conveying hopper 17 into the shredding cylinder 3, the material conveying hopper 17 is reset along the mounting frame 16 to fit against the buffer plate 21, and the buffer plate 21 realizes the buffering function by squeezing the return spring 20.
