Description

Technical Field

[0001] The utility model relates to the technical field of bamboo fiber processing, in particular to a bamboo raw material crushing device for bamboo fiber production. Background Art

[0002] Bamboo fiber is cellulose fiber extracted from naturally grown bamboo. Bamboo fiber has good air permeability, instant water absorption, strong wear resistance and good dyeability. It has natural antibacterial, antibacterial, mite removal, deodorization and UV resistance. The processing of bamboo fiber is a relatively cumbersome process. It needs to go through multiple processing steps to obtain high-quality bamboo fiber.

[0003] When bamboo fiber is processed, the raw bamboo needs to be broken into thin strips. The commonly used crushing device is a shredder, which splits the bamboo into smaller states and discharges them from the slits at the bottom. When discharged, the thin bamboo strips are squeezed by the bamboo above and discharged from the discharge bottom plate. When the thin bamboo strips are stuck, it is difficult to discharge from the hole, which not only affects the subsequent bamboo processing but also causes the equipment to get stuck, increases the frequency of maintenance, and is not conducive to the use of the equipment.

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0021] like Figure 1-Figure 4As shown, a bamboo raw material crushing device for bamboo fiber production provided in this embodiment includes a crushing box 1, knife grooves 12 are welded on both sides of the inner wall of the crushing box 1, a crushing roller 3 slides in the knife groove 12, bearings are raised at both ends of the crushing roller 3 and are rotatably connected to the inner wall of the crushing box 1, one end of the crushing roller 3 is externally connected to a power box 8, an arc-shaped leak plate 5 is welded at the bottom of the knife groove 12, a scraper shaft 10 is slidably connected to the bottom of the arc-shaped leak plate 5, a pull rod 11 is arranged at the bottom of the scraper shaft 10, and a hydraulic rod 9 is rotatably connected to the middle of the pull rod 11.

[0022] The power box 8 includes a driving motor and a driving gear. A rectangular gap is formed on the arc-shaped leaking plate 5. Slide grooves 13 are provided on both sides of the outer wall of the arc-shaped leaking plate 5. The fixing frame 14 can slide freely in the slide groove 13.

[0023] A fixing frame 14 is slidably disposed in the slide groove 13 . The fixing frame 14 is clamped and connected with the three groups of scraper shafts 10 . A fixing plate 6 is welded to one side of the outer wall of the fixing frame 14 .

[0024] The outer ends of the pull rod 11 are rotatably connected to the fixed plate 6, and the other end of the hydraulic rod 9 is rotatably connected to the rotating support seat 7. The rotating support seat 7 is welded to the inner wall of the crushing box 1. The hydraulic rod 9 can move the scraper shaft 10 along the bottom arc of the arc-shaped leak plate 5 through the rotating support seat 7 and the pull rod 11, and the reciprocating motion can achieve scraping and washing.

[0025] A feeding trough 2 is riveted on the top of the crushing box 1, and a material discharge inclined plate 4 is fixedly installed on the bottom of the crushing box 1. The feeding trough 2 is used to feed longer bamboo strips.

[0026] An operation panel 16 is embedded on the outer wall of the crushing box 1 , and the operation panel 16 is externally connected to a driving power source. A scraping thorn 15 is welded on the top of the scraper shaft 10 , and the scraping thorn 15 is made of alloy material. The operation panel 16 is connected to the motor wire in the power box 8 .

[0027] Working principle of this device: When this device is used, it is connected to an external power supply, and the motor in the power box 8 is started through the operation panel 16 to drive the crushing roller 3 to engage and rotate. The user puts the bamboo raw material from the feed trough 2 into the crushing box 1, and it is engaged and crushed by the crushing roller 3. The crushed bamboo falls onto the arc-shaped leak plate 5, and the smaller bamboo is discharged from the arc-shaped leak plate 5 with pressure, and the larger bamboo is rolled up by the crushing roller 3 to continue crushing. When the small bamboo is discharged, some of it will be stuck in the slit hole, affecting the discharge of other bamboos. At this time, the bottom hydraulic rod 9 pulls the pull rod 11, and the pull rod 11 moves in an arc along the fixed frame 14 in the slide groove 13 on both sides of the arc-shaped leak plate 5, and drives the three groups of scraper shafts 10 to slide back and forth at the bottom of the arc-shaped leak plate 5. The scraper 15 moves along the gap, which can quickly bring out the bamboo to be discharged from the gap, improve the discharge efficiency of the bamboo, and avoid clogging in the gap. This design can greatly reduce the clogging frequency of the equipment, reduce maintenance time, and improve processing efficiency.
