[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

Therefore, the invention is not limited to the specific embodiments disclosed below.

In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0034] Example 1 Reference Figures 1-9 This is the first embodiment of the present invention, which provides a method for quantitatively conveying cementitious powder.

[0035] Feed tank 100; The feed hole 101 is used to feed the adhesive powder into the feed tank 100; The conveyor box 102 is connected to the bottom of the feed tank 100; The conveying pipe 103 connects to the left and right sides of the conveying box 102; First, the adhesive powder is fed into the feed tank 100 through the feed hole 101; Next, the reciprocating motor 201b is started to drive the rotating rod 202a to perform reciprocating and rotating motion; Finally, by rotating the rotating rod 202a in a reciprocating motion, the cementitious powder stored in the receiving cavity 301b can be dislodged from the receiving cavity 301b by the centrifugal force generated during rotation and fall into the conveying box 102. The rotating component 202 enables the rotating rod 202a to rotate during reciprocating motion, causing the cementitious powder entering the receiving cavity 301b to be detached from the receiving cavity 301b by the centrifugal force generated during rotation. The amount of cementitious powder stored in the receiving cavity 301b can be adjusted by adjusting the component 302. After the adhesive powder is put into the feed tank 100, the reciprocating motor 201b drives the reciprocating gear 201c to rotate, which drives the reciprocating tooth plate 201d to move up and down, thereby causing the rotating rod 202a to rise and fall with it. At the same time, the rotating rod 202a can rotate during the lifting and lowering process through the cooperation of the threaded groove 202b and the threaded sleeve 202c.

[0036] Example 2 Reference Figures 1-4 This is the second embodiment of the present invention, which provides a reciprocating mechanism 200.

[0037] The reciprocating mechanism 200 is used to quantitatively convey the adhesive powder into the conveying box 102; The reciprocating mechanism 200 includes a drive assembly 201 disposed on the top of the feed tank 100, and a rotating component 202 disposed at the bottom of the drive assembly 201; The drive assembly 201 includes a fixed base 201a fixedly connected to the top of the feed tank 100. A reciprocating motor 201b is provided on the front side of the fixed base 201a. A reciprocating gear 201c is driven to the output end of the reciprocating motor 201b. A reciprocating tooth plate 201d meshes with the surface of the reciprocating gear 201c. The rotating component 202 includes a rotating rod 202a disposed at the bottom of the reciprocating toothed plate 201d. The bottom of the rotating rod 202a extends into the interior of the feed tank 100. A threaded groove 202b is provided in the upward-facing middle part of the rotating rod 202a. A threaded sleeve 202c is provided on the outer side of the rotating rod 202a. Several connecting pieces 202d are provided on the outer side of the threaded sleeve 202c. The outer sides of the several connecting pieces 202d are all fixedly connected to the inner side of the feed tank 100. A connecting crossbar 404 is fixedly connected to the surface of the rotating rod 202a, and stirring rods 405 are provided at both ends of the top of the connecting crossbar 404.

[0038] Specifically, the use of the drive component 201 can drive the feeding component 301 to move up and down reciprocally. The use of the rotating component 202 can rotate the feeding component 301 when it moves downward, generating centrifugal force to throw the adhesive powder out of the receiving cavity 301b.

[0039] Furthermore, when the reciprocating motor 201b starts, its output end drives the reciprocating gear 201c to rotate. Since the reciprocating gear 201c meshes with the reciprocating toothed plate 201d, the reciprocating toothed plate 201d will move up and down accordingly. The up and down movement of the reciprocating toothed plate 201d drives the rotating rod 202a to rise and fall synchronously. The threaded groove 202b on the rotating rod 202a cooperates with the fixed threaded sleeve 202c. During the rising and falling process, the rotating rod 202a will rotate. The rotation of the rotating rod 202a drives the connecting crossbar 404 and the stirring rod 405 to rotate, stirring the cementitious powder in the feed tank 100.

[0040] Preferably, a reciprocating drive device can be provided at the connection between the connecting crossbar 404 and the stirring rod 405, so that the stirring rod 405 can reciprocate when the connecting crossbar 404 and the stirring rod 405 rotate, thereby increasing the stirring area.

[0041] Example 3 Reference Figure 2 , Figures 5-9 This is the third embodiment of the present invention, which provides an expansion mechanism 300.

[0042] The expansion mechanism 300 is used to adjust the amount of adhesive powder conveyed into the conveying box 102; The expansion mechanism 300 includes a feeding assembly 301 disposed inside the feeding tank 100, and an adjustment component 302 disposed inside the feeding assembly 301. The feeding assembly 301 includes a feeding ring 301a disposed at the bottom of the rotating rod 202a. The outer side of the feeding ring 301a is provided with a plurality of receiving cavities 301b. The inner side of the plurality of receiving cavities 301b is provided with a plurality of receiving plates 301c. The opposite side of the plurality of receiving plates 301c is fixedly connected to a telescopic plate 301d. The adjusting component 302 includes an adjusting groove 302a opened inside the feeding ring 301a. A miniature push rod 302b is fixedly connected to the surface of the adjusting groove 302a. A pressure ring 302c is drivenly connected to the output end of the miniature push rod 302b. Several pressure rods 302d are provided at the bottom of the pressure ring 302c. An extension groove 302e is opened from the outside to the inside of the adjusting groove 302a. A rotating gear 302f is provided on the inner side of the extension groove 302e. The top of the rotating gear 302f is fixedly connected to the bottom of several receiving plates 301c. An annular groove 303 is provided on the inner side of the adjusting groove 302a. Several arc-shaped toothed plates 304 are slidably connected to the surface of the annular groove 303. A pressure groove 305 is provided on the outer side of each of the several arc-shaped toothed plates 304. A pressure column 306 is provided on the surface of the pressure groove 305. One side of each pressure column 306 is fixedly connected to one side of each of the several pressure rods 302d. The surfaces of the several arc-shaped toothed plates 304 mesh with the surface of the rotating gear 302f. A fixed vertical rod 401 is fixedly connected to the bottom of the threaded sleeve 202c. The fixed vertical rod 401 is sleeved on the outside of the rotating rod 202a. A fixed box 402 is provided on the outside of the fixed vertical rod 401. A micro motor 403 is provided on the inside of the fixed box 402. A first gear 4031 is connected to the output end of the micro motor 403. A second gear 4032 is connected to the surface of the first gear 4031. A first rotating shell 4033 is provided at the bottom of the second gear 4032. A second rotating shell 4034 is provided at the bottom of the first rotating shell 4033. Several through slots 4035 are provided on the upper and lower sides of both the first rotating shell 4033 and the second rotating shell 4034.

[0043] Specifically, the amount of adhesive powder entering the receiving cavity 301b at a time can be adjusted by using the adjusting component 302.

[0044] Furthermore, when it is necessary to adjust the amount of cementitious powder conveyed, the micro push rod 302b is activated and pushes the pressure ring 302c to move downward along the adjustment groove 302a. The pressure ring 302c drives the pressure rod 302d to move downward synchronously. The pressure rod 302d squeezes the pressure groove 305 of the arc-shaped toothed plate 304 through the pressure column 306, causing the arc-shaped toothed plate 304 to slide along the annular groove 303. The arc-shaped toothed plate 304 meshes with the rotating gear 302f, driving the rotating gear 302f to rotate in the extension groove 302e, thereby driving the receiving plates 301c to move closer or further away from each other. When the receiving plates 301c move closer, the telescopic plate 301d stretches, the volume of the receiving cavity 301b increases, and the amount of cementitious powder conveyed in a single batch increases. When the receiving plates 301c move further away, the telescopic plate 301d folds, the volume of the receiving cavity 301b decreases, and the amount of cementitious powder conveyed in a single batch decreases.

[0045] Preferably, a heating device can be provided in the first rotating shell 4033 and the second rotating shell 4034 to heat the cementitious powder that is about to enter the receiving cavity 301b, thereby reducing the risk of blockage.

[0046] It should be noted that when the slots 4035 of the first rotating shell 4033 and the second rotating shell 4034 are aligned, the adhesive powder can fall into the receiving cavity 301b; conversely, when they are misaligned, the adhesive powder is blocked.

[0047] The remaining structure is the same as that in the embodiment.

[0048] Example 4 Reference Figures 1-9 This is the fourth embodiment of the present invention, which differs from the first embodiment in that: this embodiment provides a quantitative conveying device for cementitious powder.

[0049] When using this quantitative delivery device; First, the adhesive powder is fed into the feed tank 100 through the feed hole 101. Under the action of gravity, the adhesive powder initially accumulates at the bottom of the feed tank 100, in preparation for subsequent conveying. Next, the reciprocating motor 201b is started, and its output end drives the reciprocating gear 201c to rotate. Since the reciprocating gear 201c meshes with the reciprocating gear plate 201d, the reciprocating gear plate 201d moves up and down, thereby driving the rotating rod 202a to move up and down synchronously. At the same time, the threaded groove 202b in the middle of the rotating rod 202a cooperates with the threaded sleeve 202c fixed inside the feed tank 100, generating rotational motion during the lifting process, so that the rotating rod 202a can simultaneously achieve reciprocating movement and rotation. Finally, the reciprocating motion of the rotating rod 202a drives the bottom feeding ring 301a to move synchronously. The solid powder stored in the receiving cavity 301b is released from the receiving cavity 301b under the action of centrifugal force generated by the rotation and falls into the conveying box 102 below, and then is conveyed to the target position through the conveying pipe 103. The rotating component 202 enables the rotating rod 202a to rotate during reciprocating motion. On one hand, this subjectes the cementitious powder entering the receiving cavity 301b to centrifugal force, ensuring it completely detaches from the cavity and preventing residue from causing quantitative errors. On the other hand, the rotational motion, combined with the reciprocating lifting motion, allows the receiving cavity 301b to evenly receive the cementitious powder from the feed tank 100, improving the uniformity of feeding. By adjusting the component 302, the amount of cementitious powder stored in the receiving cavity 301b can be adjusted according to actual needs, thereby achieving precise control of different conveying volumes and meeting diverse application scenarios. During the lifting process, the rotating rod 202a will rotate. The rotation of the rotating rod 202a will drive the connecting crossbar 404 and the stirring rod 405 to rotate, which will stir the adhesive powder in the feed tank 100, prevent the adhesive powder from clumping due to excessive accumulation time, ensure its fluidity, and ensure that it can smoothly enter the receiving cavity 301b. When the amount of cementitious powder conveyed needs to be adjusted, the micro push rod 302b is activated and pushes the pressure ring 302c to move downward along the adjustment groove 302a. The pressure ring 302c drives the pressure rod 302d to move downward synchronously. The pressure rod 302d squeezes the pressure groove 305 of the arc-shaped toothed plate 304 through the pressure column 306, causing the arc-shaped toothed plate 304 to slide along the annular groove 303. The arc-shaped toothed plate 304 meshes with the rotating gear 302f, driving the rotating gear 302f to rotate in the extension groove 302e, thereby driving the receiving plates 301c to move closer or further apart. When the receiving plates 301c move closer, the telescopic plate 301d stretches, the volume of the receiving cavity 301b increases, and the amount of cementitious powder conveyed in a single operation increases. When the receiving plates 301c move further apart, the telescopic plate 301d folds, the volume of the receiving cavity 301b decreases, and the amount of cementitious powder conveyed in a single operation decreases. When storing adhesive powder in the receiving cavity 301b, the micro motor 403 drives the first gear 4031 to rotate, and the second gear 4032 drives the first rotating shell 4033 to rotate, so that the positions of the first rotating shell 4033 and the through groove 4035 of the second rotating shell 4034 are opposite, so that the adhesive powder can fall into the receiving cavity 301b. Conversely, after the adhesive powder is stored in the receiving cavity 301b, the micro motor 403 is started again, so that the positions of the first rotating shell 4033 and the through groove 4035 of the second rotating shell 4034 are misaligned, stopping the feeding of adhesive powder and blocking it.

[0050] In summary, by setting up the reciprocating mechanism 200 and the expansion mechanism 300, the opening and closing angle of the receiving plate 301c can be flexibly adjusted to change the volume of the receiving cavity 301b, thereby meeting the conveying requirements under different working conditions.
