[0002] With the continuous improvement of environmental awareness, people's demand for green and environmentally friendly materials is growing. Industrial hemp stalks, as a renewable resource, have good mechanical properties and environmental protection characteristics and can be used to make boards. When using industrial hemp stalks to make boards, the industrial hemp stalks need to be cleaned first, and then divided into small sections of a certain length and put into the crusher for crushing. Then the industrial hemp stalk fragments are added to the glue mixer for glue mixing. Then, the molding mechanism can be used to press it, and finally it is dried to complete the production of the board.

[0003] Among them, in order to ensure the quality of board production, the most important step is to ensure that the industrial hemp stem fragments can be evenly coated with glue, which is the key to the board having a certain strength and stability. Therefore, when the glue mixer is mixing the glue, it takes a long time to mix the glue, and the efficiency of board production needs to be further improved. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a device for making boards from industrial hemp stalks that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic idea of the technical solution adopted by the present invention is: a device for making boards from industrial hemp stalks, including a feed barrel, and also including: an annular jet shell, installed at the drop-out port at the lower end of the feed barrel; a jet head, connected to the inner wall of the annular jet shell at equidistant intervals on the circumference, and the jet head is arranged tilted upward; an annular groove is provided in the feed barrel near the top of the annular jet shell; an annular glue storage shell is installed in the annular groove of the feed barrel, and the inner wall of the annular glue storage shell and the inner wall of the feed barrel are on the same annular surface; a plurality of glue spray heads are connected to the inner wall of the annular glue storage shell at equidistant intervals on the circumference, the glue spray heads are embedded in the annular glue storage shell, and the glue spray ports of the glue spray heads and the inner wall of the annular glue storage shell are on the same annular surface; a sealing disk is provided at the upper inner end of the feed barrel, and a plurality of rows of filter holes are provided on the sealing disk.

[0006] In order to facilitate the quantitative addition of industrial hemp stalk fragments into the feeding barrel, the device further includes a feeding barrel, which is laterally fixedly connected to the upper end of one side of the feeding barrel, and is connected to the feeding barrel. A feeding funnel is connected to the upper side of the feeding barrel away from the feeding barrel, and a motor is fixedly connected to the side of the feeding barrel close to the feeding funnel. A spiral quantitative pusher is rotatably connected in the feeding barrel, and the end of the spiral quantitative pusher away from the feeding barrel is fixedly connected to the output end of the motor.

[0007] In order to prevent the industrial hemp stalk fragments wrapped in glue from adhering to the delivery barrel, the upper end of the feed barrel is further fixedly connected to an electric telescopic rod through a bracket, and the sealing plate is slidably connected in the feed barrel and fixedly connected to the telescopic end of the electric telescopic rod.

[0008] In order to facilitate the dredging of the filter hole and keep it unobstructed, further, the lower end surface of the bracket is fixedly connected with a mounting ring, and the lower end of the mounting ring is fixedly connected with a dredging rod used in conjunction with the filter hole.

[0009] In order to facilitate the sufficient scraping of the materials attached to the wall of the feeding cylinder, the lower surface of the sealing disk is further designed to be an inner arc shape.

[0010] In order to facilitate the staff to quickly remove the annular jet shell from the feeding barrel, further, a mounting shell is threadedly connected to the drop port of the feeding barrel, and the annular jet shell is installed in the mounting shell.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model uses the feeding barrel, the annular jet shell, the jet head, the annular glue storage shell, the glue spray head and the sealing plate and other components in combination. Compared with the prior art method of directly using a glue mixer to mix the industrial hemp stalk fragments with glue, the industrial hemp stalk fragments can be pre-coated with glue in the process of adding the industrial hemp stalk fragments to the glue mixer through the feeding barrel. Therefore, when the pre-coated industrial hemp stalk fragments are put into the glue mixer for glue mixing, the time required for glue mixing can be effectively shortened without affecting the uniformity of glue mixing, thereby effectively improving the efficiency of board production.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example 1:

[0021] Reference Figures 1-4 , a device for making boards from industrial hemp stalks, includes a feeding barrel 1, and also includes: an annular jet shell 102, which is installed at the blanking port at the lower end of the feeding barrel 1; a jet head 103, which is equidistantly connected to the inner wall of the annular jet shell 102 at a circumferential distance, and the jet head 103 is arranged tilted upward; an annular groove is provided in the feeding barrel 1 near the top of the annular jet shell 102; an annular glue storage shell 104 is installed in the annular groove of the feeding barrel 1, and the inner wall of the annular glue storage shell 104 and the inner wall of the feeding barrel 1 are on the same annular surface; a plurality of glue spraying heads are equidistantly connected to the inner wall of the annular glue storage shell 104 at a circumferential distance, and the glue spraying heads are embedded in the annular glue storage shell 104, and the glue spraying ports of the glue spraying heads are on the same annular surface as the inner wall of the annular glue storage shell 104; a sealing disk 107 is provided at the upper end of the interior of the feeding barrel 1, and a plurality of rows of filter holes 108 are provided on the sealing disk 107.

[0022] When it is necessary to add industrial hemp stalk fragments into the glue mixer for stirring and mixing, the staff first sets the feed barrel 1 just above the feed port of the glue mixer, and then delivers gas into the annular jet shell 102, and then multiple jet heads 103 will simultaneously spray gas obliquely upward. When the gas reaches the position of the sealing disk 107, the gas will be discharged from the feed barrel 1 through the filter holes 108 on the sealing disk 107. When the industrial hemp stalk fragments are added into the feed barrel 1, the industrial hemp stalk fragments blown by the wind will be located in the feed barrel 1 under the obstruction of the sealing disk 107. By controlling the flow rate of the gas, the height of the industrial hemp stalk fragments circling in the feed barrel 1 can be controlled.

[0023] When the jet head 103 is started to jet, a certain amount of industrial hemp stem fragments can be added to the feed barrel 1, and then the industrial hemp stem fragments will swirl in the feed barrel 1 under the influence of the airflow, and then pressure can be applied to the annular glue storage shell 104, and then the glue in the annular glue storage shell 104 will be sprayed into the feed barrel 1 in the form of mist through the glue spray head under the effect of extrusion, and then the industrial hemp stem fragments will be mixed with the glue. When the industrial hemp stem fragments are mixed with the glue, the mass of the industrial hemp stem fragments will increase, so that they will overcome the lifting force of the airflow and fall out of the feed barrel 1, and then the industrial hemp stem fragments pre-mixed with the glue will be added to the glue mixer, and then the glue mixer is started again, and the industrial hemp stem fragments and the glue can be stirred and mixed again. When the glue mixing process of the industrial hemp stem fragments is completed, they can be taken out of the glue mixer for the next step of sheet material forming.

[0024] Through the coordinated use of components such as the feeding barrel 1, the annular air jet shell 102, the air jet head 103, the annular rubber storage shell 104, the glue spray head and the sealing disk 107, compared with the method of directly using a glue mixer to mix the industrial hemp stem fragments with glue in the prior art, in the process of adding the industrial hemp stem fragments to the glue mixer through the feeding barrel 1, the industrial hemp stem fragments can be pre-coated with glue, so that when the pre-coated industrial hemp stem fragments are put into the glue mixer for glue mixing, the time required for glue mixing will not be affected while the uniformity of glue mixing will be effectively shortened, thereby effectively improving the efficiency of board production.

[0025] Example 2:

[0026] Reference Figures 1-4, a device for making boards from industrial hemp stalks, which is basically the same as Example 1, further comprising: a feeding cylinder 2, which is fixedly connected to the upper end of one side of the feeding cylinder 1 in a horizontal direction, the feeding cylinder 2 is connected to the feeding cylinder 1, and a feeding funnel 201 is connected to the upper side of the feeding cylinder 2 away from the feeding cylinder 1, and a motor 202 is fixedly connected to the side of the feeding cylinder 2 close to the feeding funnel 201, and a spiral quantitative pusher 203 is rotatably connected in the feeding cylinder 2, and the end of the spiral quantitative pusher 203 away from the feeding cylinder 1 is fixedly connected to the output end of the motor 202, During use, the staff first connects the feed funnel 201 with the discharge port of the compressor, and then the industrial hemp stalk fragments crushed by the compressor will fall into the delivery barrel 2 through the feed funnel 201, and then the spiral quantitative pusher 203 is driven to rotate by the motor 202, and the spiral quantitative pusher 203 will transport the crushed industrial hemp stalk fragments into the delivery barrel 1 for pre-coating, and by controlling the number of revolutions of the spiral quantitative pusher 203 each time, the amount of industrial hemp stalk fragments added each time can be controlled, thereby achieving precise quantity control.

[0027] The upper end of the feeding barrel 1 is fixedly connected to the electric telescopic rod 106 through the bracket 105, and the sealing plate 107 is slidably connected to the feeding barrel 1 and fixedly connected to the telescopic end of the electric telescopic rod 106. Through the setting of the electric telescopic rod 106, when the spiral quantitative pusher 203 conveys a certain amount of industrial hemp stalk fragments into the feeding barrel 1, the sealing plate 107 can be controlled to move downward through the electric telescopic rod 106 so that it is located below the feeding barrel 2, and then the air jet 103 blows air into the feeding barrel 1 so that the industrial hemp stalk fragments swirl in the feeding barrel 1. The industrial hemp stalk fragments adhered to glue will not float into the feeding barrel 2, thereby avoiding the industrial hemp stalk fragments wrapped in glue from adhering to the feeding barrel 2, affecting the material transportation and material waste.

[0028] The lower end face of the bracket 105 is fixedly connected with a mounting ring 109, and the lower end of the mounting ring 109 is fixedly connected with a dredging rod 1010 used in conjunction with the filter hole 108. Through the setting of the mounting ring 109 and the dredging rod 1010, when the filter hole 108 on the sealing disk 107 is blocked by some fine debris, the sealing disk 107 can be controlled by the electric telescopic rod 106 to move up and down a short distance, so that the dredging rod 1010 can be inserted back and forth into the filter hole 108 to dredge the filter hole 108, thereby ensuring the smooth passage of gas through the filter hole 108.

[0029] like Figure 3As shown, the lower surface of the sealing plate 107 is designed to be an inner arc. When the sealing plate 107 moves downward to scrape off the stem fragments attached to the inner wall of the feed barrel 1 by glue, the stems mixed with glue can be moved along the arc surface of the sealing plate 107 toward the middle of the sealing plate 107. Then, when the sealing plate 107 moves down and out of the feed barrel 1, the staff can scrape off the stems adhered to the sealing plate 107, which effectively improves the effect of removing the material adhered to the inner wall of the feed barrel 1.

[0030] Example 3:

[0031] Reference Figures 1-4 , a device for making boards from industrial hemp stalks, which is basically the same as Example 2, further comprising: a mounting shell 101 is threadedly connected to the drop port of the feeding barrel 1, and the annular jet shell 102 is installed in the mounting shell 101. By making the annular jet shell 102 detachable and mounted on the feeding barrel 1 through the mounting shell 101, when the annular jet shell 102 and the jet head 103 need to be disassembled, repaired or replaced, it is convenient for the staff to quickly remove them from the feeding barrel 1, providing convenience for the staff.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
