[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the hammering head is driven by a linear cylinder to move and hammer the bamboo material. When the hammering head collides with the material, its recoil force will be transmitted to the linear cylinder through the hammering head, causing damage to the linear cylinder. At the same time, if the linear cylinder slowly contacts and hammers the bamboo material with the pneumatic hammering head, the hammering effect on the bamboo material is not good. If the linear cylinder accumulates force and is suddenly pushed out for hammering, the linear cylinder will be greatly damaged, reducing the service life of the device.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a bamboo papermaking beating device, which includes a crossbeam plate 1, a beating cylinder 2 is installed in the middle of the top of the crossbeam plate 1, a beating cavity 21 is opened at the center of the top of the beating cylinder 2, a cleaning drive source 7 is installed on one side of the top of the crossbeam plate 1, and scrapers 8 for cleaning the inner wall surface of the beating cavity 21 are installed on both sides of the driving end of the cleaning drive source 7;

[0030] Electric telescopic rods 3 are installed on both sides of the top of the crossbeam plate 1. The movable end of the electric telescopic rod 3 is fixedly connected to the lifting plate 4 through a connecting column. The distance between the hammer head 6 and the bottom of the hammering cavity 21 can be adjusted by the extension and retraction of the electric telescopic rod 3. The distance between the hammer head 6 and the bottom of the hammering cavity 21 is adaptively adjusted according to the actual hammering progress and needs, so as to improve the hammering effect on the bamboo material and facilitate the unloading of the bamboo material after the hammering is completed. A hammering drive source 5 is installed at the middle end of the lifting plate 4. The movable end of the hammering drive source 5 is detachably installed with a hammer head 6, and the hammer head 6 and the hammering cavity 21 are coaxially arranged.

[0031] The hammer driving source 5 includes a vertical bin 51 installed at the middle opening of the top of the lifting plate 4, and the bottom of the vertical bin 51 is open. A driving block 58 is vertically slidably installed inside the vertical bin 51. The bottom end of the driving block 58 is magnetically adsorbed with a lifting block 55, and a convex edge for blocking the lifting block 55 is installed at the bottom of the vertical bin 51, and the hammer head 6 is fixed at the bottom of the lifting block 55.

[0032] An electromagnet 59 is installed at the bottom of the driving block 58, and an iron block 56 is installed at the top of the lifting block 55, and the electromagnet 59 and the iron block 56 are magnetically attracted.

[0033] A winding disk 53 is rotatably installed at the top of the vertical bin 51, and a wire rope 54 is wound around the winding disk 53, and the bottom end of the wire rope 54 is connected to the top of the driving block 58. At the same time, a round hole is opened on the top of the vertical bin 51 for the wire rope 54 to pass through. A driving motor 52 for driving the winding disk 53 to rotate is installed on the top of the vertical bin 51 through a pad, and the driving end of the driving motor 52 is connected to the shaft end of the winding disk 53.

[0034] The hammer head 6 is driven to rise reciprocatingly, and the bamboo material is continuously hammered by falling down. When the hammer head 6 is hammering the bamboo material, it is in an independent state, and the recoil force it receives will not be fed back to the driving end, thereby reducing the damage to the driving end. On the one hand, the stability of the hammering is improved, and on the other hand, the damage to the device is reduced, thereby extending the service life. The hammer head 6 can also be lifted to different heights to adjust the downward impact force of the hammer head 6 and the force of beating the bamboo material.

[0035] Guide rails 57 are installed on both sides of the vertical bin 51, and sliding grooves slidably connected to the guide rails 57 are opened on both sides of the lifting block 55 and the driving block 58, and vertical limited sliding is used to improve the stability during vertical sliding.

[0036] During use, the bamboo material is placed in the inner cavity of the hammering cavity 21, and the electric telescopic rod 3 is shortened to drive the lifting plate 4 to move downward, so that the hammer head 6 enters the interior of the hammering cavity 21;

[0037] The second driving motor 52 drives the winding disk 53 to rotate, and unwinds the steel wire rope 54 wound on the winding disk 53. The driving block 58 drops due to gravity. When the electromagnet 59 contacts the iron block 56, the electromagnet 59 turns on to generate magnetic force and magnetically adsorbs the iron block 56. The second driving motor 52 drives the winding disk 53 to rotate in the opposite direction, reels the steel wire rope 54, moves the driving block 58 upward, and under the action of the magnetic adsorption between the electromagnet 59 and the iron block 56, lifts the hammer head 6 upward. After the hammer head 6 is lifted to a high place, the electromagnet 59 is closed to release the magnetic adsorption with the iron block 56, and the hammer head 6 falls due to gravity. The downward impact force of the hammer head 6 hits the bamboo material inside the hammering cavity 21, and hammers the bamboo material.

[0041] The cleaning drive source 7 includes a chassis and a driving motor 71 installed on the chassis, and a rotating circle 73 rotatably installed on the top of the beating cylinder 2. The outer wall of the rotating circle 73 is covered with a circular rack 74, and the top of the driving motor 71 is installed with a gear 72 meshing with the circular rack 74.

[0042] During use, the driving motor 71 drives the gear 72 to rotate. Under the meshing transmission action of the gear 72 and the circular rack 74, the driving motor 71 drives the rotating circle 73 to rotate, and the scraper 8 rotates with the rotating circle 73. The scraper 8 scrapes off the bamboo material adhered to the inner wall of the beating cavity 21.
