[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] The embodiment of the present application provides a material dispersion pipe and a material conveying and stirring device, which can break up large pieces of powder during conveying, and can also start a vibrator to vibrate the large pieces of powder to prevent blockage with the pointed part, and make the powder continuously collide with the pointed part to make the powder dispersed more evenly.

[0036] like Figure 1As shown, the embodiment of the present application provides a material dispersion pipe, which may include: a first tube body 1, a pointed portion 2 is fixed inside the first tube body 1, and the tip of the pointed portion 2 faces one end of the first tube body 1 close to the material feeding device 6; a vibrator 3, and the vibrator 3 is installed on the outer wall of the first tube body 1. Exemplarily, the pointed portion 2 is fixed inside the first tube body 1 and close to the bottom end of the first tube body 1, and the tip of the pointed portion 2 is arranged in the vertical direction and faces the top end of the first tube body 1. The vibrator 3 can be installed on the left outer side wall of the first tube body 1. Among them, the installation method of the vibrator 3 and the first tube body 1 can adopt the installation method in the prior art, as long as it can be achieved that the first tube body 1 can be driven to vibrate when the vibrator 3 is started, and this embodiment of the present application will not be described in detail.

[0037] Specifically, the top end of the first tube body 1 can be connected with the output end of the material feeding device 6 in advance, and the bottom end of the first tube body 1 can be connected with the feed port of the material stirring device 5. In the process of the material feeding device 6 conveying and feeding the material stirring device 5, large pieces of powder will pass through the first tube body 1, come into contact and collide with the pointed part 2 in the first tube body 1 and be broken into pieces, and then enter the material stirring device 5 for stirring, and the vibrator 3 can also be started to vibrate the large pieces of powder to prevent blockage with the pointed part 2, and make the powder continuously collide with the pointed part 2, so that the powder is dispersed more evenly, and then enter the material stirring device 5 at a uniform and slow speed to prevent blockage of the material stirring device 5.

[0038] Furthermore, the pointed portion 2 is installed inside the first tube body 1 through a mounting bracket, the mounting bracket includes a mounting portion and a connecting portion, the pointed portion 2 is fixed to the mounting bracket through the mounting portion, and the mounting bracket is connected to the inner wall of the first tube body 1 through the connecting portion. Figure 1 As shown in the figure; illustratively, the mounting portion may include a mounting tray, which is fixed to the bottom surface of the pointed portion 2, and the mounting bracket may include a plurality of fixing rods, which are spaced around the mounting tray and fixed to the mounting tray, and the plurality of fixing rods are fixedly connected to the inner wall of the first tube body 1, so that there is space between the bottom surface of the pointed portion 2 and the side wall of the first tube body 1 to ensure that the crushed material can pass through.

[0039] Further, the pointed portion 2 includes: at least one cone, and / or at least one polygonal pyramid. When the pointed portion includes a cone or a polygonal pyramid, the cone or polygonal pyramid is coaxially arranged with the first tube 1. The bottom surface area of ​​the cone or polygonal pyramid is smaller than the cross section of the first tube, so as to ensure that the crushed material can pass through.

[0040] When the pointed portion 2 includes multiple cones or multiple polygonal pyramids, each cone or polygonal pyramid can be fixed to the inner wall of the first tube body 1 through a mounting tray and multiple fixing rods. The embodiment of the present application does not impose specific restrictions on the distribution of the multiple cones or polygonal pyramids. For example, the multiple cones or multiple polygonal pyramids can be distributed in the first tube body 1 in an annular manner. After the powder falls, it is divided by the tips of the multiple cones or multiple polygonal pyramids and falls to the material mixing device in the gaps between the multiple cones or multiple polygonal pyramids. For another example, the multiple cones or multiple polygonal pyramids can be distributed in intervals along the length direction of the first tube body 1, and the multiple cones or multiple polygonal pyramids are not coaxially arranged, that is, they are staggered along the length direction of the first tube body 1, and the extension path is S-shaped, etc.

[0041] Furthermore, the sizes of the multiple cones or multiple polygonal pyramids may be different.

[0042] The edges of the polygonal pyramid are not specifically limited and may be regular three-sided, four-sided or five-sided pyramids. The polygonal pyramid is preferably a regular polygonal pyramid.

[0043] Furthermore, a cutting blade can be fixedly attached to the side wall of the cone or polygonal pyramid, and the length direction of the cutting blade extends from the top of the cone or polygonal pyramid to the bottom of the cone or polygonal pyramid. After the large block powder collides with the tip of the cone or polygonal pyramid, it will be dispersed into a large number of small blocks of powder. At this time, the small blocks of powder will continue to move along the side wall of the cone or polygonal pyramid and continue to be divided by the cutting blade on the side wall of the cone or polygonal pyramid, thereby improving the dispersion of the powder. No additional power device is required to actively divide the material. The structure is simple and the cost is low.

[0044] In some embodiments, such as Figure 1 As shown, the material dispersing pipe may also include: a hose 4, one end of which is connected to one end of the first tube body 1. The setting of the hose 4 can facilitate the connection with the subsequent material feeding device 6, which can improve the flexibility and installation error of the material feeding device 6, and can reduce the vibration sense transmitted to the material feeding device 6 under the operation of the vibrator 3, thereby ensuring the structural integrity and service life of the material feeding device 6. Of course, the other end of the first tube body 1 can also be installed with a hose 4 and the material stirring device 5, and its advantages refer to the advantages brought by the installation of the hose 4 and the material feeding device 6.

[0045] In some embodiments, such as Figure 1As shown, the inner diameter of the hose 4 gradually decreases from the middle of the hose 4 to its two ends. When the hose 4 is subsequently installed with the material feeding device 6, if the length of the hose 4 is too long, the hose 4 can be squeezed appropriately to be compressed to connect with the material feeding device 6. The compressed hose 4 will deform along the direction of its width without affecting the subsequent powder delivery work, thereby avoiding bending of one end of the straight hose 4 due to squeezing, which affects the delivery of the powder.

[0046] In addition, if Figure 1 As shown, the embodiment of the present application can also provide a material conveying and stirring device, which may include: a first tube body 1, a pointed portion 2 is fixed inside the first tube body 1, and the tip of the pointed portion 2 is facing one end of the first tube body 1; a vibrator 3, the vibrator 3 is installed on the outer wall of the first tube body 1; a material stirring device 5, the feed port of the material stirring device 5 is connected to the other end of the first tube body 1; a material feeding device 6, the output end of the material feeding device 6 is connected to one end of the first tube body 1; a material storage device 7, the output end of the material storage device 7 is connected to the input end of the material feeding device 6.

[0047] Among them, the powder is stored in the material storage device 7, and is transported through the material feeding device 6, passes through the first tube body 1, and finally enters the material stirring device 5 for stirring. In the process of conveying and feeding from the material feeding device 6 to the material stirring device 5, large pieces of powder will pass through the first tube body 1, contact and collide with the pointed part 2 in the first tube body 1 and be broken, and then enter the material stirring device 5 for stirring, and the vibrator 3 can also be started to vibrate the large pieces of powder to prevent blockage with the pointed part 2, and make the powder continuously hit the pointed part 2, so that the powder is dispersed more evenly, and then enter the material stirring device 5 at a uniform and slow speed to prevent blockage of the material stirring device 5.

[0048] In some embodiments, the material stirring device 5 may include: a main screw machine 51, the feed port of the main screw machine 51 is connected to a second tube body 52, and the second tube body 52 is connected to the other end of the first tube body 1; a current detector, the current detector is electrically connected to the main screw machine 51; a controller, the controller is electrically connected to the main screw machine 51, the current detector and the vibrator 3, when the current fluctuation value received by the controller from the main screw machine 51 exceeds the set value, the controller controls the vibrator 3 to work. Among them, the current detector will detect the current fluctuation of the main screw machine 51. If large materials enter the material stirring device, the resistance to the rotation of the main screw machine 51 will increase, and the required torque will increase. In order to complete the rotation, the main screw machine 51 will increase the current to overcome this resistance. If the current fluctuation is too large, it means that the feeding at the feed port of the main screw machine 51 is unstable. At this time, the controller will start the vibrator 3 to work. The vibrator 3 vibrates to disperse the powder, and then it falls to the main screw machine 51 at a uniform and slow speed, which greatly improves the stability of the operation of the main screw machine 51 and prevents the main screw machine 51 from being blocked.

[0049] In some embodiments, the material mixing device 5 further includes: an alarm, which is electrically connected to the controller. When the current fluctuation of the main screw machine 51 received by the controller exceeds the setting, the controller controls the alarm to work. The controller will start the alarm according to the signal that the duration of the current fluctuation of the main screw machine 51 exceeds the set value, reminding the staff that the vibrator 3 can no longer play an effective vibration dispersion work and needs to be manually checked.

[0050] Exemplarily, the alarm may include a warning light and a sounder.

[0051] In some embodiments, one end of the first tube body 1 is connected to a hose 4 ; the material feeding device 6 includes: a feeding screw 61 , an output end of the feeding screw 61 is connected to a third tube body 62 , and the third tube body 62 is connected to the hose 4 .

[0052] In some embodiments, the material storage device 7 includes: a storage tank 71, the output end of the storage tank 71 is set in a cone shape and is connected to the input end of the material feeding device 6. Among them, the output end of the storage tank 71 is set in a cone shape, which can facilitate the complete delivery of the powder to the material feeding device 6 to prevent the powder from remaining inside for too long and affecting the processing quality.

[0053] Among them, the material storage device 7 is not limited to the storage tank 71, but can be other storage containers, the material feeding device 6 is not limited to the feeding screw machine, but can also be a conveyor belt, and the material stirring device 5 is not limited to the main screw machine 51, but can also be other stirrers.
