Description

Technical Field

[0001] This utility model relates to the field of compaction devices, and in particular to a quartz sand compaction device. Background Technology

[0002] Quartz sand is a non-metallic mineral raw material with high hardness, widely used in glass, casting, building materials and other fields. In the processing of quartz sand, it is often necessary to crush the raw material using crushing equipment to meet the requirements of subsequent processes. Currently, common quartz sand crushing devices mainly adopt a counter-rotating roller structure, where the quartz sand is squeezed and crushed by the clamping force formed between two relatively rotating rollers.

[0003] However, in the aforementioned structure, the prolonged compaction of quartz sand in the same location can easily lead to excessive localized wear in the center of the compaction roller or a specific stress area. This results in decreased compaction efficiency, uneven product particle size, and frequent equipment maintenance. While some devices can improve the output particle size by adjusting the compaction gap, this does not effectively solve the problem of localized wear on the compaction roller. Furthermore, due to the somewhat random distribution of quartz sand, a lack of dynamic adjustment capabilities during the compaction process can lead to issues such as central agglomeration and concentrated stress paths, affecting compaction uniformity and product quality. Utility Model Content

[0004] This invention provides a quartz sand compaction device that can solve the problems of excessive wear of the compaction rollers and uneven force caused by a single compaction path in the existing rotary roller compaction structure.

[0006] Support structure, feeding and discharging components, transmission mechanism, and moving mechanism.

[0007] The moving mechanism includes a fixed shaft, a second gear rotatably connected to the fixed shaft, a slide rod fixedly connected to the second gear, a second grinding wheel movably sleeved on the fixed shaft, a sliding groove on the second grinding wheel, the sliding groove being slidably connected to the slide rod, a blind hole at the end of the second grinding wheel away from the second gear, a fixing pin fixedly connected inside the blind hole, a fixing wheel fixedly connected at the end of the fixed shaft away from the second gear, an annular groove on the outer circumference of the fixing wheel, the fixing pin being movably connected inside the annular groove, and the two ends of the fixed shaft being fixedly mounted on two fixed seats.

[0008] Preferably, the support structure includes a worktable, and the fixed base is mounted on the worktable.

[0009] Preferably, the feeding and discharging assembly includes a crushing chamber, and the second crushing wheel is located inside the crushing chamber.

[0010] Preferably, the transmission mechanism includes a first gear that meshes with a second gear.

[0011] Preferably, a screen is provided at the lower opening of the compaction chamber.

[0012] Preferably, the worktable is rectangular, and a rectangular hole is provided near the center.

[0013] Preferably, the feeding and discharging assembly further includes a feeding bin, which is located above the workbench and has a funnel-shaped structure that is wider at the top and narrower at the bottom.

[0014] Preferably, a discharge port is fixedly connected to the bottom surface of the workbench.

[0015] Preferably, the transmission mechanism further includes a third gear that meshes with the second gear.

[0016] Preferably, the third gear is fitted with a first grinding wheel.

[0017] Beneficial effects: This utility model achieves automatic axial movement without relying on electrical control by fixing a sliding rod to the second gear and slidably connecting the sliding rod to a groove on the second grinding wheel. This allows the second grinding wheel to rotate around a fixed axis when the second gear rotates. Simultaneously, the sliding connection structure allows the second grinding wheel to reciprocate axially during rotation. The second grinding wheel also features a fixed pin that engages with an annular groove on the fixed wheel, ensuring axial reciprocating movement along the fixed axis during rotation, preventing deviation, expanding the compaction contact area, improving compaction uniformity, and reducing localized wear. The moving mechanism, through gear meshing, the sliding rod and groove engagement, and the fixed pin and annular groove engagement, achieves automatic axial movement without relying on electrical control, resulting in a compact structure, reliable movement, and stable torque transmission.

A first gear 305 is fixedly connected to the other side of the first transmission shaft 309. Second mounting seats 311 are provided on both sides of the first gear 305. The upper end of the second mounting seat 311 is rotatably connected to the first transmission shaft 309, and its lower end is fixedly connected to the worktable 101.

[0034] The moving mechanism 400 includes a second gear 404, with a fixed shaft 408 passing through its center.

A second grinding wheel 401 is sleeved on the fixed shaft 408 and is movably connected to the fixed shaft 408. A sliding groove 402 is formed at the end of the second grinding wheel 401, and the slide rod 403 is inserted into the sliding groove 402 and slidably connected to the sliding groove 402. The fixed shaft 408 is located away from the second grinding wheel 401. One end of gear 404 is fixedly connected to a fixed wheel 409, and an annular groove 407 is provided on the fixed wheel 409. The end of the second grinding wheel 401 away from the sliding groove 402 is provided with a blind hole, the size of which is preferably large enough to accommodate the fixed wheel 409.

Fixed seats 410 are fixedly connected to both ends of the fixed shaft 408. The fixed seats 410 are fixedly connected to the worktable 101. One side of the second gear 404 is connected to the first gear 305, and the other side is connected to the third gear 307.

[0035] Working Principle: During operation, quartz sand is fed into the feed hopper 201, which is funnel-shaped and guides the quartz sand into the compaction chamber 202 below. The compaction chamber 202 contains a first grinding wheel 306 and a second grinding wheel 401, which compact the quartz sand through rotation. When the motor 301 is powered on, its output shaft drives the first pulley 302 to rotate. The first pulley 302 drives the second pulley 304 to rotate synchronously via a belt 303. The second pulley 304 is fixedly connected to the first drive shaft 309, causing the first drive shaft 309 to rotate. The first drive shaft 309 drives the first gear 305 fixed on it to rotate. The first gear 305 meshes with the second gear 404, which in turn meshes with the third gear 307. The third gear 307 drives the second drive shaft 310 fixedly connected to it to rotate, thereby driving the first grinding wheel 306 fixed on the second drive shaft 310 to perform the compaction motion. Meanwhile, the sliding rod 403 fixed on the second gear 404 slides in conjunction with the sliding groove 402 on the second grinding wheel 401, allowing the second grinding wheel 401 to slide back and forth axially along the fixed shaft 408. Simultaneously, the sliding rod 403 transmits the rotational force from the second gear 404 to the second grinding wheel 401, causing the second grinding wheel 401 to rotate around the fixed shaft 408. The other side of the second grinding wheel 401 is movably connected to the annular groove 407 on the fixed wheel 409 via a fixing pin 406, allowing the second grinding wheel 401 to slide back and forth axially along the fixed shaft 408 during rotation. This achieves periodic axial reciprocating motion of the second grinding wheel 401 during rotation, further enhancing the crushing effect and improving the crushing efficiency of the quartz sand. The crushed quartz sand particles fall from the bottom of the crushing chamber 202. Large particles that are not fully crushed cannot be discharged due to the interception of the screen 204 and will continue to circulate and be crushed within the crushing chamber 202, ensuring the uniformity and fineness of the output particle size.

[0036] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
