Description

Technical Field

[0001] This utility model relates to the field of raw material processing technology, specifically to an automatic weighing device for batching quartz raw materials. Background Technology

[0002] In utility model patent application CN211586791U, published on September 29, 2020, entitled "A Quartz Stone Raw Material Processing Equipment," this utility model discloses a quartz stone raw material processing equipment, belonging to the field of mineral processing technology. The key technical feature is a quartz stone raw material processing equipment, including a frame. A feeding port is provided at the top of the frame, and a fine material outlet and a coarse material outlet are provided at the bottom of the frame. A crushing mechanism is installed inside the frame, comprising a crushing component and a crushing power component. Below the crushing mechanism is a screening mechanism, which includes a screening component and a screening power component. The first belt drives four rotating rollers with serrated edges to rotate, crushing the quartz stone located between two adjacent rotating rollers. The first screening component and the second screening component can transport fine quartz stone, i.e., material with a particle size smaller than the sieve aperture on the first or second sieve cylinder, to the first or second conveyor belt. The fine quartz stone material is then transported to the fine material outlet via the fine material conveyor belt and the fine material discharge conveyor belt. The processing efficiency is high and the processing effect is good.

[0003] Among the patents or prior art mentioned above, the existing weighing methods mainly rely on manual operation or simple mechanical weighing, which requires manual adjustment of the material feed, is easily affected by human error, and is inefficient. This can lead to inaccurate quartz raw material ratios, affecting product quality and performance. Utility Model Content

[0004] The purpose of this invention is to provide an automatic weighing device for batching quartz raw materials, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic weighing device for quartz raw material batching, comprising a base plate, a mixing device on the base plate, two sets of mounting brackets on the mixing device, a storage box fixed between the two sets of mounting brackets, a discharge port at the bottom of the storage box, a baffle plate rotatably mounted at the discharge port via a rotating rod, limit blocks diagonally mounted at the upper and lower ends of the baffle plate, a weighing box below the storage box, the weighing box being fixed between two sets of fixed rods via connecting rods on both sides, the fixed rods being vertically fixed to the base plate, a partition plate inside the weighing box for dividing the interior into two chambers of different sizes, a discharge assembly on one side of the weighing box, and the weighing box and the baffle plate being connected via a linkage assembly.

[0006] Furthermore, the feeding assembly includes an opening on one side of the weighing box, and a rotating plate is rotatably disposed within the opening.

[0007] Furthermore, the linkage component includes a second rotating wheel fixedly sleeved on one of the connecting rods, and a first rotating wheel fixedly sleeved on the outer surface of the rotating rod, and the second rotating wheel and the first rotating wheel are connected by belt drive.

[0008] Furthermore, a limiting crossbar that cooperates with the rotating plate is fixedly provided at the top of the inner wall of the opening.

[0009] Furthermore, an inclined plate is fixedly provided at the top of the partition plate.

[0010] Furthermore, three sets of X-shaped reinforcing rods are fixedly provided between the two sets of fixed rods.

[0011] Furthermore, both ends of the fixing rod are provided with triangular reinforcing ribs, which are welded and fixed to the base plate and the fixing rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the automatic weighing device for quartz raw material batching is reasonable and has the following advantages:

[0013] (1) The device realizes automatic weighing and feeding control of quartz raw materials through mechanical linkage, which significantly improves the accuracy and efficiency of batching. The weighing box adopts the lever balance principle and achieves dynamic balance by comparing the weight of the preset weight with that of the raw material. When the weight of the raw material is insufficient, the weighing box tilts and drives the belt drive to keep the baffle open and continue feeding. When the weight reaches the standard, the weighing box returns to the horizontal and the baffle closes automatically, forming a closed-loop control. This design avoids the batching deviation caused by visual error or operation delay in traditional manual weighing, and is especially suitable for quartz production with strict requirements for batching ratio.

[0014] (2) The device prevents material leakage after weighing by designing arc-shaped limiting blocks. The limiting blocks of the baffle are arranged in an arc-shaped diagonal, and their movement trajectory is completely matched with the baffle. During the weighing stage, it is allowed to open and close freely. During unloading, the baffle is forcibly locked by mechanical clamping to prevent accidental leakage of raw materials. This dual-state design ensures functional flexibility and eliminates the risk of misoperation. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 The present invention provides a technical solution as follows:

[0025] Example 1:

[0026] An automatic weighing device for quartz raw material batching includes a base plate 100, a mixing device 101 on the base plate 100, two sets of mounting brackets 102 on the mixing device 101, a storage box 103 fixed between the two sets of mounting brackets 102, a discharge port 104 at the bottom of the storage box 103, a baffle 105 rotatably mounted at the discharge port 104 via a rotating rod 107, limiting blocks 106 diagonally positioned at the upper and lower ends of the baffle 105, a weighing box 300 below the storage box 103, the weighing box 300 being fixed between two sets of fixing rods 200 via connecting rods 301 on both sides, the fixing rods 200 being vertically fixed on the base plate 100, a partition plate 307 inside the weighing box 300 for dividing the interior into two chambers of different sizes, a discharge assembly on one side of the weighing box 300, and the weighing box 300 being connected to the baffle 105 via a linkage assembly.

[0027] The feeding assembly includes an opening 304 on one side of the weighing box 300, and a rotating plate 305 is rotatably disposed within the opening 304.

[0028] The linkage component includes a second rotating wheel 302 fixedly sleeved on one of the connecting rods 301, and a first rotating wheel 108 fixedly sleeved on the outer surface of the rotating rod 107. The second rotating wheel 302 and the first rotating wheel 108 are connected by a belt 303.

[0029] The top of the inner wall of the opening 304 is fixedly provided with a limiting crossbar 306 that cooperates with the rotating plate 305.

[0030] An inclined plate 308 is fixedly provided at the top of the partition plate 307.

[0031] Three sets of X-shaped reinforcing rods 201 are fixedly provided between the two sets of fixed rods 200.

[0032] Both ends of the fixing rod 200 are provided with triangular reinforcing ribs 202, and the reinforcing ribs 202 are welded and fixed to the base plate 100 and the fixing rod 200.

[0033] Working Principle: During use, the operator places the corresponding weights into the smaller chamber of the weighing box 300 according to the requirements. At this time, the weighing box 300 tilts to one side. A limiting support rod is located below the chamber of the weighing box 300 near the weights. The limiting support rod is installed on the reinforcing rod 201, which holds the weighing box 300 in place to prevent excessive descent. The quartz raw material is stored in the storage box 103. The second rotating wheel 302 rotates as the weighing box 300 tilts, driving the first rotating wheel 108 and the baffle 105 to rotate via the belt 303, thus opening the discharge port 104. The quartz raw material in the storage box 103 falls into the larger chamber of the weighing box 300 through the discharge port 104. When the weight of the raw material equals the weight of the weights, the weighing box 300 reaches a horizontal state. The rotation angle of the weighing box 300 changes, causing the baffle 105 to close via the belt 303, stopping the discharge. The operator only needs to slightly lift the weighing box 300. The material in the raw material chamber presses against the rotating plate 305, causing it to rotate around its axis and open. The material is then discharged into the mixing device 101 through the opening 304. Limiting blocks 106 are diagonally arranged at the upper and lower ends of the baffle 105. Their arc shape matches the movement trajectory of the baffle 105. When the weighing box 300 is lifted, the edge of the baffle 105 is stopped by the limiting blocks 106, forcibly preventing further rotation and ensuring the baffle 105 remains closed to prevent material leakage. During the weighing process, the limiting blocks 106 do not affect the normal opening and closing of the baffle 105; they only function during the unloading stage to prevent uncontrolled material discharge due to misoperation. The inclined plate 308 prevents raw material from entering the chamber containing the weights. The reinforcing rod 201 and triangular reinforcing rib 202 enhance the rigidity of the overall frame, preventing vibration from affecting weighing accuracy.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
