It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0042] In order to solve the above problems, according to the concept of one aspect of the utility model, by setting multiple groups of independently adjustable licker-in roller assemblies 2, impurities adhering to the surface of raw materials can be effectively removed, solving the problem that impurities on the surface of raw materials affect subsequent processing and production.

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0044] Figure 1 It is a schematic diagram of the three-dimensional structure of a dust removal device with hidden brackets and side panels according to an exemplary embodiment of the utility model.

[0045] According to the utility model, a dust removal device suitable for a flaker is provided, such as Figure 1As shown, it includes a dust removal channel 1 and multiple groups of licker-in roller assemblies 2. The dust removal channel 1 is arranged between the flaker 9 and the wood pulling channel 7. Multiple groups of licker-in roller assemblies 2 are arranged in sequence along the axis of the dust removal channel 1, and each group of licker-in roller assemblies 2 includes at least one licker-in roller 21 and a driving motor 22. Both ends of the licker-in roller 21 are rotatably arranged on the side wall of the dust removal channel 1. The driving motor 22 is connected to the licker-in roller 21 in a transmission connection. Among them, the rotation speeds of the licker-in rollers 21 of the multiple groups of licker-in roller assemblies 2 are increased in sequence along the material transmission direction to pull the piled materials apart, so as to remove the surface of the material and the impurities adhering to the surface.

[0046] According to the above arrangement, multiple groups of licker-in roller assemblies 2 are sequentially arranged in the dust removal channel 1 along the material transmission direction, and are respectively driven to rotate by the driving motor 22. The rotation speeds of the licker-in rollers 21 of the multiple groups of licker-in roller assemblies 2 along the material transmission direction are sequentially increased, so that the accumulated materials transported by the wood pulling channel 7 can be broken up and the spacing can be widened. At the same time, since the rotation speeds of each group of licker-in roller assemblies 2 are different, it is beneficial to remove the epidermis of the materials on the two groups of licker-in roller assemblies 2 and the impurities adhering to the epidermis.

[0047] In an illustrative embodiment, Figure 1 As shown, a feeding channel 8 is provided between the dust removal channel 1 and the flaker 9 , which is suitable for receiving the dust-removed material from the dust removal channel 1 and conveying it to the inside of the flaker 9 .

[0048] In an illustrative embodiment, Figure 1 As shown, the feeding channel 8 includes a conveyor belt assembly, wherein the conveying surface height of the conveyor belt assembly is lower than the output surface height of the dust removal channel 1.

[0049] In an illustrative embodiment, the wood pulling channel 7 includes a chain transmission assembly. Optionally, a plurality of chain conveyor lines are arranged in the wood pulling channel 7. Since the materials are mostly raw materials such as branches, wood, bamboo, etc., the uneven surface and pores of the chain conveyor lines can be used to better convey the materials. In addition, the pores of the chain conveyor belt can also facilitate the falling of mud blocks adhered to the surface of the material, thereby reducing the dust generated during the shaving process.

[0050] In an illustrative embodiment, optionally, the drive motor 22 is a variable frequency speed regulating motor.

[0051] Figure 2 It is a schematic diagram of the three-dimensional structure of the licker-in roller assembly of the dust removal equipment according to the exemplary embodiment of the utility model.

[0052] In an illustrative embodiment, Figure 1 and Figure 2As shown, each group of licker-in roller assemblies 2 includes a driving motor 22, which is transmission-connected to a plurality of licker-in rollers 21, and the rotation speeds of the licker-in rollers 21 are the same. The rotation speed of the driving motor 22 in each group of licker-in roller assemblies 2 gradually increases along the material transmission direction, and the piled material can be split and adjusted by utilizing the rotation speed difference of adjacent licker-in roller assemblies 2. Taking a 1-meter bamboo pole as the material as an example, when the front end of the bamboo pole enters the second group of licker-in roller assemblies 2, the forward speed of the bamboo pole is equivalent to the linear speed of the rotation of the licker-in roller 21 of the first group of licker-in roller assemblies 2. Based on the rotation speed difference between the two groups of licker-in roller assemblies 2, the thorns on the licker-in roller 21 of the second group of licker-in roller assemblies 2 slide relative to the front end of the bamboo pole, based on which part of the bamboo skin or adhered soil on the surface of the front end of the bamboo pole can be peeled off, and the peeled bamboo skin or soil falls from the gap between the licker-in rollers 21. As the bamboo pole is continuously transported forward, the area crossed by the licker-in roller 21 of the second licker-in roller assembly 2 gradually increases, the force of the licker-in roller 21 of the second licker-in roller assembly 2 on the bamboo pole continues to increase, and the force of the first licker-in roller assembly 2 on the bamboo pole continues to decrease, until the two are equal, the conveying speed of the bamboo pole changes, and is equal to the linear speed of the rotation of the licker-in roller 21 of the second licker-in roller assembly 2. At this point, the licker-in roller 21 of the first licker-in roller assembly 2 crosses the bamboo pole and removes the bamboo skin and the attached soil in the back half of the bamboo pole. Further, when the licker-in roller 21 crosses the surface of the bamboo pole, a certain vibration will occur, and this vibration can be conducive to dispersing the piled raw materials; further, when the conveying speed of the lowest layer directly in contact with the licker-in roller 21 changes, the raw materials of the lowest layer can be extracted from the "pile" raw materials, thereby achieving the purpose of spacing the piled materials apart and feeding them evenly.

[0053] According to the above-mentioned setting, when the dust removal equipment is working, the speed of the drive motor 22 driving the licker-in assembly 2 can be adjusted according to the amount of material transmitted by the wood pulling channel 7, so as to break up the accumulated materials and open up the spacing, and effectively remove the surface of the materials and impurities adhered to the surface.

[0054] In an illustrative embodiment, Figure 1 As shown, the dust removal device further comprises a conveyor belt 3, which is arranged at the bottom of the dust removal channel 1. The conveyor belt 3 is suitable for conveying the surface of the material peeled off by the licker-in roller 21 to the next process.

[0055] In an illustrative embodiment, Figure 2 As shown, the licker-in roller 21 includes a roller shaft 211, a roller 212, and a plurality of protrusions 213. The roller shaft 211 is rotatably arranged at both ends on the side wall of the dust removal passage 1, and the roller shaft 211 is in driving connection with the driving motor 22. The roller 212 is arranged on the roller shaft 211, and the roller 212 rotates concentrically and at the same speed as the roller shaft 211. A plurality of protrusions 213 are arranged in an array on the outer side wall of the roller 212, and the protrusions 213 are conical.

[0056] According to the above-mentioned setting method, a plurality of conical protrusions 213 are arranged in an array on the outer wall of the roller 212. During the process of rotating and conveying the material, the conical protrusions 213 can contact various positions on the surface of the material to effectively remove the surface of the material and impurities adhering to the surface. At the same time, the conical protrusions 213 will not hook the material, causing the material to hang on the licker-in roller 21, thereby affecting the dust removal effect.

[0057] Figure 3 is a top view of a dust removal passage of a dust removal device according to an exemplary embodiment of the present utility model.

[0058] In an illustrative embodiment, the number of the licker-in roller assemblies 2 is 3 to 8 groups.

[0059] In an illustrative embodiment, the number of the licker-in rollers 21 in each licker-in roller assembly 2 is 2 to 6.

[0060] According to the above-mentioned setting method, the dust removal equipment can select the number of licker-in roller assemblies 2 and the number of licker-in rollers 21 of the licker-in roller assemblies 2 according to the length of the material to be dusted, the amount of impurities adhered to the surface of the material, and the required dust removal effect, so that the dust removal equipment can work efficiently and meet the dust removal requirements at the same time.

[0061] In an exemplary embodiment, the distance between two adjacent licker-in rollers 21 ranges from 1 to 6 cm.

[0062] According to the above arrangement, the dust removal equipment can set the spacing between the licker-in rollers 21 according to the size of the dusted material and the size of the adhered impurities, so that the material will not slip between the licker-in rollers 21, but the removed material skin and impurities can pass through.

[0063] Figure 4 It is a three-dimensional schematic diagram of the overall application scenario of the dust removal equipment according to the exemplary embodiment of the present utility model.

[0064] In an illustrative embodiment, Figure 4 As shown, the dust removal device further includes a bracket 4 and a side plate 5. The bracket 4 is arranged below the dust removal passage 1, and the conveyor belt 3 is arranged inside the bracket 4. The side plate 5 is detachably mounted on the side of the bracket 4, and the side plate 5 cooperates with the bracket 4 and the dust removal passage 1 to define a relatively sealed passage.

[0065] According to the above-mentioned setting mode, a detachable side plate 5 is arranged on the side of the bracket 4. When there are a lot of materials, the accumulated materials may slide down from the side in the dust removal channel 1, and the side plate 5 can prevent the materials from sliding down. When there are less materials, the side plate 5 is removed to facilitate the observation of the dust removal effect of the materials and to adjust according to the dust removal effect. At the same time, the side plate 5 cooperates with the bracket 4 and the dust removal channel 1 to define a relatively sealed channel, so that the removed material skin and impurities adhered to the skin can only fall between the licker-in rollers 21 to the conveyor belt 3 arranged inside the bracket 4.

[0066] In an illustrative embodiment, the upper end of the side plate 5 may be inclined toward the outside of the dust removal passage 1 .

[0067] According to the above-mentioned arrangement, the space between the inclined side plates 5 at both ends is larger, so that more materials transmitted from the wood pulling channel 7 can be received, while preventing the materials from slipping due to excessive materials.

[0068] In an illustrative embodiment, baffles may be installed between the brackets 4 .

[0069] According to the above-mentioned configuration, installing baffles between the brackets 4 can effectively prevent the fallen material surface and impurities adhered to the surface from falling to the outside of the transmission path and polluting the working environment.

[0070] In an illustrative embodiment, Figure 2 As shown, the dust removal device also includes a reducer 23, which is arranged at the output end of the driving motor 22. The reducer 23 is suitable for increasing the output torque of the driving motor 22.

[0071] According to the above configuration, the reducer 23 can convert the high-speed rotation of the driving motor 22 into a low-speed rotation, reduce the output speed of the driving motor 22, and improve the stability of the licker-in assembly 2. Secondly, the reducer 23 can amplify the output torque, improve the transmission efficiency, and enable the licker-in assembly 2 to easily drive the material to move.

[0072] Figure 5 It is a schematic diagram of the three-dimensional structure of a sensor of a dust removal device according to an exemplary embodiment of the present utility model.

[0073] In an illustrative embodiment, Figure 5 As shown, the dust removal device further includes a plurality of groups of sensors 6 which are arranged at the upstream end of the dust removal channel 1 in the vertical direction. The plurality of groups of sensors 6 are suitable for obtaining the height of the material entering the dust removal channel 1 .

[0074] Optionally, multiple groups of sensors 6 are arranged in sequence along the vertical direction at the upstream end of the dust removal channel 1, adjacent to the wood pulling channel 7. The sensors 6 emit rays in the horizontal direction. When the material passes through, the height of the material in the dust removal channel 1 can be obtained according to the position where the material blocks the rays, and the rotation speed of each licker-in roller assembly 2 and the rotation speed difference between the licker-in rollers 21 are adjusted according to the material height, so that the dust removal power is matched with the current amount of material being transmitted, saving dust removal costs. Further optionally, the sensor 6 is an infrared sensor.

[0075] In an alternative exemplary embodiment, the sensor 6 further includes an ultrasonic sensor and a laser sensor.
