Description

Technical Field

[0001] The utility model relates to the technical field of fiberboard production, in particular to a chipping device for fiberboard production. Background Art

[0002] Fiberboard is made from wood fiber, processed through fiber preparation, applied with synthetic resin, and pressed under heat and pressure. Due to its uniform structure, fine material, stable performance, impact resistance, and ease of processing, it is widely used in domestic furniture, interior decoration, and composite wood flooring. The product is in short supply and has a very optimistic market outlook. During the fiberboard production process, chippers are used to remove excess fiberboard into small chips, allowing this excess wood to be repurposed into industries such as textiles, papermaking, and pulping.

[0003] However, existing chippers lack screening measures and cannot screen the small wood chips cut by the chipper into qualified and unqualified ones. Many of these chipped small wood chips are oversized and often do not meet the subsequent use requirements. All small wood chips need to be processed again, which greatly affects the processing efficiency. Therefore, a chipping device for fiberboard production is proposed. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a chipping device for fiberboard production includes a shell body 1, a feed port 2 is provided at the front end of the shell body 1, a qualified discharge port 3 is provided at the bottom of the shell body 1, and a defective product discharge port 4 is provided on the rear end side wall of the shell body 1. A rotating roller 16 is rotatably installed inside the shell body 1, and the axial end of the rotating roller 16 is connected to a driving mechanism. A plurality of grooves 17 are provided on the outer surface of the rotating roller 16, and the plurality of grooves 17 are distributed in a ring array. A cutting blade 18 is fixedly connected to one side of the groove 17 of the rotating roller 16, and a sieve plate 12 is provided at the bottom of the rotating roller 16 in the shell body 1, and one end of the sieve plate 12 is rotatably connected to the bottom of the feed port 2, and a vibration mechanism is provided below the sieve plate 12, and a plurality of filter holes 14 are provided on the sieve plate 12.

[0021] Among them, the driving mechanism consists of motor No. 1 5, driving gear 6, driven gear 7 and transmission belt 8. Motor No. 1 is fixedly connected to the outer wall of the shell 1. The output shaft of motor No. 1 is fixedly connected to the driving gear 6. The shaft end of the rotating roller 16 is fixedly connected to the driven gear 7. The outer surfaces of the driven gear 7 and the driving gear 6 are covered with transmission belt 8 and are respectively engaged with the transmission belt 8.

[0022] When in use, start the No. 1 motor 5 to drive the driving gear 6 to rotate. Under the action of the transmission belt 8, the driven gear 7 will start to rotate, thereby driving the rotating roller 16 to rotate. The cutting blade 18 on the rotating roller 16 will cut the fiberboard entering the interior of the shell 1.

[0023] The diameter of the driving gear 6 is smaller than the diameter of the driven gear 7 .

[0024] With such an arrangement, a labor-saving gear set can be formed between the driving gear 6 and the driven gear 7 , thereby reducing the stress on the output shaft of the first motor 5 .

[0025] Among them, the vibration mechanism is composed of a No. 2 motor 9, a rotating shaft 10, a cam 11 and a spring 13. The cam 11 is located below the sieve plate 12. The two ends of the cam 11 are rotatably connected to the two inner walls of the shell 1 through two rotating shafts 10. The No. 2 motor 9 is fixedly connected to the outer wall of the shell 1. The output shaft of the No. 2 motor 9 is fixedly connected to the axial end of a rotating shaft 10. Multiple springs 13 are fixedly connected between the bottom of the sieve plate 12 and the bottom of the inner cavity of the shell 1. The multiple springs 13 are distributed in a linear array.

[0026] When in use, start the No. 2 motor 9 to drive the rotating shaft 10 and the cam 11 to rotate. The protrusion on the cam 11 will push the sieve plate 12 upward. When the protrusion on the cam 11 is away from the sieve plate 12, the spring 13 provided at the bottom of the sieve plate 12 can ensure that the sieve plate 12 can be quickly reset, thereby achieving the purpose of vibrating the sieve plate 12.

[0027] The end of the sieve plate 12 is connected to an extension plate 15 , and the extension plate 15 is located inside the defective product discharge port 4 .

[0028] Such an arrangement can ensure that the defective wood chips brought up by the rotating roller 16 will not fall from the gap between the screen plate 12 and the defective product discharge port 4, ensuring that the defective wood chips can smoothly enter the defective product discharge port 4.

[0029] The utility model provides a chipping device for fiberboard production, and the specific working principle is as follows:

[0030] During use, the fiberboard is fed into the feed port 2 through the feeding structure (the feeding structure can adopt the common transmission structure of the chipper, which is not the main content of this application and will not be described here), and at the same time, the No. 1 motor 5 is started to drive the driving gear 6 to rotate. Under the action of the transmission belt 8, the driven gear 7 will start to rotate, thereby driving the rotating roller 16 to rotate, and the cutting blade 18 on the rotating roller 16 will cut the fiberboard entering the shell 1. The cut wood chips will fall on the screen plate 12, and the vibration of the screen plate 12 is controlled by the vibration mechanism. The wood chips of qualified size will fall through the filter holes 14 on the screen plate 12 and be discharged through the qualified discharge port 3, while the unqualified wood chips will remain on the screen plate 12 and continue to accumulate. When the unqualified wood chips exceed a certain height, they will be pushed upward by the inner wall of the groove 17 on the rotating roller 16, so that they will be discharged from the defective product discharge port 4, thereby achieving the purpose of quickly separating qualified wood chips from unqualified wood chips.

[0031] Working principle of the vibration mechanism: Start the No. 2 motor 9 to drive the rotating shaft 10 and the cam 11 to rotate. The protrusion on the cam 11 will push the sieve plate 12 upward. When the protrusion on the cam 11 is away from the sieve plate 12, the spring 13 provided at the bottom of the sieve plate 12 can ensure that the sieve plate 12 can be quickly reset, thereby achieving the purpose of vibrating the sieve plate 12.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
