Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a wood veneer crusher. Background Technology

[0002] In the timber processing industry, logs produce a large amount of bark after processing. To facilitate recycling, the bark can be crushed and used for boiler combustion, ensuring complete combustion. However, due to its irregular shape and light weight, bark is difficult to feed into a crusher. Existing technology, patent application CN201310407810.4, discloses a bark crusher, including a base, a conveying structure, and a crushing structure. The conveying structure includes a conveyor chain and a feeding roller, which can clamp the bark into the crushing mechanism. However, the clamping capacity of its feeding roller is limited, especially since some light or short wood chips tend to float, causing the bark to accumulate at the input end. Once the accumulation reaches a certain height, it becomes even more difficult to continue conveying it forward. Summary of the Invention

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figures 1 to 4As shown, this utility model provides a wood veneer crusher, including a crusher body 100, a feeding conveyor belt 200, a discharge conveyor belt 300, and a pressing feed roller 400. The output end of the feeding conveyor belt 200 is connected to the input end of the crusher body 100, and the input end of the discharge conveyor belt 300 is connected to the output end of the crusher body 100. A spring lifting assembly 500 is provided on the output end of the feeding conveyor belt 200. The pressing feed roller 400 is rotatably mounted on the lower end of the spring lifting assembly 500 and is located above the output end of the feeding conveyor belt 200. The crusher body 100 adopts existing technology, such as a twin-shaft crusher, which will not be described in detail in this application; the discharge conveyor belt 300 can be an inclined conveyor belt.

[0025] In one specific embodiment of this application, the pressure feeding roller 400 does not have a rotational power source. During operation, the wood veneer conveyed by the feeding conveyor belt 200 can rotate due to friction as it is being conveyed forward, thus achieving the purpose of clamping and feeding. Of course, in another embodiment, to ensure synchronous rotation between the pressure feeding roller 400 and the feeding conveyor belt 200, a rotary motor can be used to drive the pressure feeding roller 400 to rotate, or a synchronous belt can be used to connect the shafts of the pressure feeding roller 400 and the feeding conveyor belt 200. In addition, a plurality of pressure feeding grooves 420 are spaced apart along the axial direction on the outer periphery of the pressure feeding roller 400, so that some of the floating wood chips can fall into the pressure feeding grooves 420 and enter the crusher body 100 as the pressure feeding roller 400 rotates.

[0026] See Figures 1 to 3 In a specific embodiment of this application, the elastic lifting assembly 500 includes a bracket 510 and a lifting frame 520. The two ends of the bottom of the bracket 510 are respectively installed on both sides of the output end of the feeding conveyor belt 200. The two ends of the bottom of the lifting frame 520 are movably inserted into the two ends of the bracket 510. An elastic tension member 530 is detachably installed between the tops of the bracket 510 and the lifting frame 520. The pressure feeding roller 400 is rotatably installed between the two ends of the bottom of the lifting frame 520. Because the wood veneer conveyed on the feeding conveyor belt 200 has a certain stacking height, the stacked wood veneer can push the pressure feeding roller 400 upwards, causing the lifting frame 520 to generate an upward force. The elastic tension member 530 can then generate a downward pulling force, ensuring that the pressure feeding roller 400 can always press against the conveyed wood veneer, ensuring the effect of elastically pressing and conveying the wood veneer.

[0027] Specifically, the support 510 includes two sets of uprights 511, which are respectively installed on both sides of the output end of the feeding conveyor belt 200. A first crossbar 512 is provided on the upper end of each set of uprights 511, and a lifting groove 513 is provided on each set of uprights 511. The two ends of the bottom of the lifting frame 520 are respectively movably inserted into the two sets of lifting grooves 513. The lifting frame 520 includes two sets of insert rods 521, whose lower ends are respectively movably inserted into the two sets of lifting grooves 513. A second crossbar 522 is provided on the upper end of each set of insert rods 521. The elastic tension member 530 is detachably installed between the first crossbar 512 and the second crossbar 522. The pressure feeding roller 400 is rotatably installed between the lower ends of the two sets of insert rods 521. The insert rods 521 can move up and down within the lifting grooves 513.

[0028] The elastic tension member 530 includes two sets of tension springs 531. Mounting brackets 532 are provided at both ends of the top of the first crossbar 512. Through slots 533 are provided on the opposite side of the two sets of mounting brackets 532. Hook rods 534 are provided in the through slots 533. Hook rings 523 are provided at the bottom of the second crossbar 522 at the position corresponding to the hook rods 534. The two ends of the two sets of tension springs 531 can be detachably mounted on the corresponding hook rods 534 and hook rings 523 by hooks 535 respectively. When there is no veneer being conveyed or the stack height of the conveyed veneer is low, the pressure feeding roller 400 is at its lowest point, and the tension spring 531 is in a relatively compressed state. When the stack height of the conveyed veneer increases to push the pressure feeding roller 400 upward, the insertion rod 521 will move upward and pull the tension spring 531 open. At this time, the tension spring 531 is in a relatively stretched state, ensuring that the pressure feeding roller 400 can always press against the conveyed veneer to achieve the purpose of elastically pressing and conveying the veneer.

[0029] Furthermore, to facilitate the installation of the pressure feeding roller 400, each of the two sets of insert rods 521 is provided with a mounting block 524 at its lower end. Both ends of the pressure feeding roller 400 are rotatably mounted on the two sets of mounting blocks 524 via a rotating shaft 410. In addition, to guide the lifting and lowering movement of the mounting blocks 524, each of the two sets of mounting blocks 524 is provided with a sliding groove 525 on both sides. Each side of the lifting groove 513 is provided with a limiting slide rail 514 along the height direction that can cooperate with the sliding groove 525.

[0030] This utility model discloses a wood veneer crusher. Wood veneer is conveyed to the crusher body 100 by a feeding conveyor belt 200 for crushing. A pressure feeding roller 400 is installed on the output end of the feeding conveyor belt 200. The pressure feeding roller 400 can rotate synchronously with the forward movement of the feeding conveyor belt 200 to press the wood veneer into the crusher body 100 for crushing, preventing the wood veneer from floating or sliding. In addition, the height of the pressure feeding roller 400 can be adaptively adjusted by a spring lifting component 500, which can adjust according to the accumulation height of the wood veneer on the feeding conveyor belt 200 to ensure that the wood veneer can be smoothly pressed into the crusher body 100.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
