DETAILED DESCRIPTION

[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0030] like Figures 1 to 5As shown, a material conveying device of an embodiment of the present invention includes a conveying cylinder 1, a partition plate 2 and a material blocking mechanism 3; the conveying cylinder 1 can rotate around its axis; the partition plate 2 is arranged in the conveying cylinder 1, and the thickness direction of the partition plate 2 extends along the axial direction of the conveying cylinder 1, the peripheral wall surface of the partition plate 2 is connected to the inner wall surface of the conveying cylinder 1, and the partition plate 2 has a first material feeding hole 201 and a second material feeding hole 202 penetrating along its thickness direction; the material blocking mechanism 3 includes a driving assembly 31 and a material blocking member 32, the driving assembly 31 is connected to the partition plate 2, the material blocking member 32 is connected to the driving assembly 31, and the driving assembly 31 drives the material blocking member 32 to move so that the material blocking member 32 blocks at least part of the second material feeding hole 202 or is staggered with the second material feeding hole 202.

[0031] In the material conveying device of the present invention, the conveying cylinder 1 rotates around its axis to realize mixed conveying of materials. A partition plate 2 is provided in the conveying cylinder 1, and a first material feed hole 201 and a second material feed hole 202 are provided on the partition plate 2. The first material feed hole 201 and the second material feed hole 202 form a channel for material conveying. In actual application, the material conveying device can drive the blocking member 32 to block the second material feed hole 202 through the driving component 31 to partially close the above-mentioned channel. The blocking member 32 will block the output of part of the material, thereby extending the time the material stays in the material conveying device, so that the material has a relatively good mixing effect.

[0032] When the material conveying device needs to accelerate the delivery of materials, the drive assembly 31 drives the material stopper 32 to move so that the material stopper 32 no longer blocks the second material delivery hole 202. At this time, the above-mentioned channel is completely open, thereby enabling the rapid delivery of materials. In addition, the drive assembly 31 serves to provide the driving force for driving the material stopper 32. The specific structure of the drive assembly 31 can adopt the structure of the following embodiment, or it can adopt the power component capable of driving the material stopper 32 in the prior art, without limitation.

[0033] For example, the second feed hole 202 can be interconnected with the first feed hole 201. In this embodiment, when the drive assembly 31 drives the blocking member 32 to move, and the blocking member 32 does not block the second feed hole 202, the first feed hole 201 and the second feed hole 202 are in a mutually connected state, making it easier for materials to pass through, ensuring smoother material transportation.

[0034] In another embodiment, the first material feeding hole 201 and the second material feeding hole 202 may be disconnected. In this embodiment, when the material blocking member 32 does not block the second material feeding hole 202, the material will pass through the first material feeding hole 201 and the second material feeding hole 202 respectively. Since the first material feeding hole 201 and the second material feeding hole 202 are disconnected, some of the material may be blocked, but this does not affect the continuous conveying, mixing, and residence time adjustment of the material.

[0035] In summary, in order to ensure smoother material transportation, preferably, the first material feeding hole 201 and the second material feeding hole 202 of this embodiment are connected to each other.

[0036] like Figure 2 and Figure 3 As shown, the first feed hole 201 is located at the center of the partition plate 2, and the number of the second feed holes 202 is multiple, and the multiple second feed holes 202 are arranged at intervals around the center of the partition plate 2; the number of the blocking mechanisms 3 is multiple, and each second feed hole 202 is correspondingly provided with a blocking mechanism 3. The setting of multiple second feed holes 202 ensures that the above-mentioned channel has sufficient flow space, and the channel can quickly output the material when it is fully open, and the number of blocking mechanisms 3 is adapted to the number of the second feed holes 202. Thus, the degree of shielding of the corresponding second feed hole 202 by each blocking member 32 is controlled separately, so that the shielded area of ​​each second feed hole 202 is the same or different, and the residence time of the material in the conveying cylinder 1 can be flexibly controlled, thereby enabling the material to have a better mixing effect.

[0037] like Figure 2 As shown, the material retaining member 32 is plate-shaped, with one surface positioned against the partition plate 2 and the other surface directly or indirectly connected to the drive assembly 31. In other words, the material retaining member 32 can be connected directly to the drive assembly 31 through its surface or indirectly through an auxiliary member. Furthermore, the area of ​​the material retaining member 32 is greater than or equal to the area of ​​the second feed hole 202. Thus, if desired, the material retaining member 32 can completely obscure the second feed hole 202, further extending the material's residence time within the conveyor barrel 1.

[0038] It should be noted that the purpose of setting the area of ​​the material stopper 32 to be greater than or equal to the area of ​​the second feed hole 202 is to ensure that the material stopper 32 can at least partially block the second feed hole 202, thereby extending the time the material remains within the material conveying device. If the area of ​​the material stopper 32 is smaller than the area of ​​the second feed hole 202, the blocking effect of the material stopper 32 on the second feed hole 202 will be greatly reduced, which is not conducive to extending the residence time of the material within the conveying device. Preferably, in this embodiment, the area of ​​the material stopper 32 is set to be larger than the area of ​​the second feed hole 202.

[0039] like Figure 2 As shown, the material blocking mechanism 3 also includes a guide rail 33 and a sliding member 34. The guide rail 33 is connected to the partition plate 2. The end of the sliding member 34 is slidably connected to the guide rail 33, and the sliding member 34 connects the material blocking member 32 and the driving assembly 31. The setting of the guide rail 33 can ensure that the material blocking member 32 moves smoothly along the predetermined straight line direction, ensuring that the material blocking member 32 can smoothly cover the second material feeding hole 202.

[0040] like Figure 4 As shown, the drive assembly 31 includes a motor 311, a screw rod 312 and a nut 313. The motor 311 is connected to the partition plate 2, the screw rod 312 is connected to the power output end of the motor 311, the nut 313 is connected to the screw rod 312, and the nut 313 is connected to the sliding member 34. The guide rail 33 is parallel to the screw rod 312. When it is necessary to extend the residence time of the material in the conveying cylinder 1, the motor 311 drives the screw rod 312 to rotate, so that the nut 313 moves along the length direction of the screw rod 312 to drive the sliding member 34 to make a straight The linear movement drives the material blocking member 32 to move to block at least part of the second feed hole 202. The advantage of the driving component 31 of this structure is that the pitch of the screw rod 312 is a fixed value. Every time the nut 313 rotates one circle, the distance moved along the axial direction of the screw rod 312 is equal to the pitch of the screw rod 312. Therefore, by controlling the rotation angle of the motor 311, the moving distance of the nut 313 can be accurately controlled to achieve precise positioning. Based on this, the moving distance of the material blocking member 32 can be accurately controlled, which is beneficial to controlling the residence time of the material in the conveying cylinder 1.

[0041] It should be noted that the power supply and control of the motor 311 can be achieved through a slip ring so that the motor can rotate along with the conveying drum 1. The specific setting method is designed according to the actual application, and this application will not elaborate on this.

[0042] like Figure 2 As shown, the motor 311 is arranged on the side of the second material feeding hole 202 away from the first material feeding hole 201, and the screw rod 312 extends radially along the conveying cylinder 1. The setting position of the motor 311 is reasonable, and the position between the inner and outer edges of the partition plate 2 is fully utilized. The material conveying device has a compact structure.

[0043] Further, such as Figure 2 As shown, there are two guide rails 33, and the two guide rails 33 are respectively arranged on opposite sides of the second material feeding hole 202; the sliding member 34 includes a connecting rod 341 and a reinforcing plate 342, and the number of the connecting rods 341 is at least two, and the two ends of the connecting rod 341 along its length direction are respectively slidably connected to the two guide rails 33, and the two adjacent connecting rods 341 are connected by the reinforcing plate 342; the material blocking member 32 is connected to the side of the connecting rod 341 close to the second material feeding hole 202, and the nut 313 is connected to the middle part of the connecting rod 341. Specifically, there are at least two connecting rods 341, and the connecting rod 341 can stably connect the material blocking member 32 and enable the material blocking member 32 to move smoothly, and the two adjacent connecting rods 341 are connected by the reinforcing plate 342. Therefore, the sliding member 34 has the advantages of stable and reliable structure.

[0044] Further, such as Figure 1 、 Figure 2 and Figure 5As shown, the material conveying device also includes a plurality of conveying plates 4, which are arranged at intervals around the first material feeding hole 201. In the axial direction of the conveying cylinder 1, one end of the conveying plate 4 is connected to the partition plate 2, and the other end extends a preset distance along the axial direction of the conveying cylinder 1. In the radial direction of the conveying cylinder 1, one end of the conveying plate 4 is connected to the inner wall surface of the conveying cylinder 1, and the other end is bent to form a material guiding groove 401. The material guiding groove 401 is connected to the first material feeding hole 201, and the material guiding groove 401 is inclined from the center of the conveying cylinder 1 to the inner wall surface of the conveying cylinder 1 in the radial direction of the conveying cylinder 1 along the direction away from the partition plate 2. Along the circumferential direction of the conveying cylinder 1, each conveying plate 4 is bent to the same side to form the material guiding groove 401, and the other opposite side is a smooth surface. Specifically, as shown in FIG. Figure 1 As shown, the left side of the conveying cylinder 1 is the feeding side, and the right side is the discharging side. Based on the setting of the conveying plate 4, when the conveying cylinder 1 rotates forward (as shown in FIG. Figure 2 As shown visually, positive rotation means rotation from right to left), at this time, the material guide groove 401 will transport the material toward the feed side, increase the residence time of the material, and at the same time perform multi-directional mixing on it, including reciprocating forced mixing along the axial direction of the conveying cylinder 1, and radial free mixing relying on gravity, so that the mixing is more uniform and the mixing efficiency is higher. When the conveying cylinder 1 is reversed, the smooth surface of the conveying plate 4 will transport the material toward the discharge side, and all the remaining materials can be discharged from the cylinder, realizing self-cleaning of the cylinder, reducing the time and difficulty of cleaning the machine and switching production, reducing the use cost, and increasing work efficiency.

[0045] like Figure 1 and Figure 2 As shown, the material blocking mechanism 3 and the conveying plate 4 are respectively arranged on both sides of the partition plate 2 in the axial direction of the conveying cylinder 1. At this time, the space on the opposite sides of the partition plate 2 is fully utilized to facilitate the installation of the material blocking mechanism 3 and the conveying plate 4.

[0046] like Figure 1 As shown, there are at least two partition plates 2, and each partition plate 2 is provided with a material blocking mechanism 3 and a conveying plate 4, thereby effectively extending the residence time of the material in the conveying cylinder 1 and achieving a better mixing effect of the material.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
