Abstract
Description
Technical Field
[0001] This utility model relates to the field of raw material mixing technology for glass polishing pads, specifically a raw material mixing device for the production of glass polishing pads. Background Technology
[0002] In the production of glass polishing pads, the uniform mixing of raw materials is a crucial factor affecting product quality. Glass polishing pads are typically composed of a polymer substrate, abrasive particles (such as cerium oxide and alumina), and additives. Their performance (such as polishing efficiency and surface roughness) directly depends on the uniformity of the raw material dispersion. Traditional mixing devices often employ fixed stirring paddles or stirring mechanisms with a single rotation direction, which suffer from the following technical defects: insufficient mixing uniformity. Due to differences in raw material viscosity or particle sedimentation, fixed stirring paddles tend to form laminar flow within the mixing tank, leading to uneven mixing in the vertical direction. This can result in abrasive agglomeration or substrate delamination in localized areas. Therefore, a raw material mixing device for glass polishing pad production is proposed to address these issues.

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0016] This invention features a rotating mechanism and a vertical moving mechanism. A drive motor is activated, causing the rotating mechanism to rotate at high speed.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] In the embodiments, by Figure 1-3 A raw material mixing device for the production of glass polishing pads is provided, comprising a mixing cylinder 1, a top cover 2 threadedly connected to the inner side of the mixing cylinder 1, a drive motor 3 fixedly connected to the top of the top cover 2, a rotating mechanism 4 fixedly connected to the output end of the drive motor 3, a vertical moving mechanism 5 provided on the rotating mechanism 4, and eight mixing rods 6 fixedly connected to the vertical moving mechanism 5.
[0023] With the above settings, the drive motor 3 is started, which drives the rotating mechanism 4 to rotate at high speed, causing the up-and-down moving mechanism 5 and the stirring rod 6 fixed on the rotating mechanism 4 to rotate synchronously. During the rotation, the stirring rod 6 stirs the raw materials (such as polymer particles, abrasives, solvents, etc.) in the mixing tank 1, breaking up the agglomeration of the raw materials. The up-and-down moving mechanism 5 drives the stirring rod 6 to periodically rise and fall along the axis of the mixing tank 1, covering the raw material layers at different heights, avoiding bottom sedimentation and top floating matter stratification. The superposition of rotation and lifting motion causes the stirring rod 6 to form a spiral trajectory in the tank, enhancing the axial and radial fluidity of the raw materials and achieving rapid and uniform mixing. After mixing is completed, the motor is stopped, the top cover 2 is unscrewed, and the raw material slurry is poured out. Compared with the existing technology, it ensures uniform mixing in the vertical direction and avoids abrasive agglomeration or substrate stratification.
[0024] Reference Figure 1-3 The rotating mechanism 4 includes a drive shaft 41. The output end of the drive motor 3 is fixedly connected to the drive shaft 41. One end of the drive shaft 41 passes through and extends to the inside of the mixing tank 1. A horizontal plate 42 is fixedly connected to the bottom end of the drive shaft 41.
[0025] With the above-mentioned structural configuration, the drive motor 3 drives the drive shaft 41 to rotate, which in turn drives the horizontal plate 42 to rotate.
[0026] Reference Figure 1-3The up-and-down moving mechanism 5 includes a base plate 51. The left end of the horizontal plate 42 is fixedly connected to the base plate 51. Two rotating shafts 52 are rotatably connected to the inner side of the base plate 51. The left ends of the two rotating shafts 52 are fixedly connected to a disk 53. The left ends of the two disks 53 are fixedly connected to a fixing post 54. The fixing post 54 is located at a position away from the center of the disk 53. The outer sides of the two fixing posts 54 are fixedly connected to a connecting rod 55. The left end of the connecting rod 55 is fixedly connected to a main rod 56. Eight stirring rods 6 are fixedly connected to the outer side of the main rod 56. A transmission mechanism 57 is provided between the rear rotating shaft 52 and the drive shaft 41.
[0027] With the above structural configuration, the drive motor 3 drives the drive shaft 41 to rotate. The drive shaft 41 transmits power to the rear rotating shaft 52 through the transmission mechanism 57, causing the two rotating shafts 52 to rotate synchronously. The rotating shaft 52 drives the disc 53 to rotate. The fixed column 54, being off-center from the disc 53, performs circular motion around the axis of the rotating shaft 52. One end of the connecting rod 55 is hinged to the fixed column 54, and the other end is connected to the main rod 56, converting the circular motion of the disc 53 into linear reciprocating motion. This forces the main rod 56 to periodically rise and fall in the vertical direction. The main rod 56 is affected by the rotation of the drive shaft 41. The eight stirring rods 6 are driven to revolve around the central axis of the mixing cylinder 1 (the whole cylinder rotates); at the same time, the main rod 56 is pulled up and down by the connecting rod 55, so that the stirring rods 6 are superimposed on the axial lifting and lowering on the basis of the revolution, forming a spiral stirring trajectory. The rotation of the stirring rods 6 covers the radial section of the mixing cylinder 1, and the up and down movement covers the raw material layers of different heights. The superposition of the two eliminates the mixing dead corners at the top, middle and bottom of the cylinder. By adjusting the speed of the drive shaft 41 or the transmission ratio of the transmission mechanism 57, the lifting and lowering frequency of the main rod 56 can be changed to adapt to the mixing needs from low viscosity solvents to high viscosity colloids.
[0028] Reference Figure 1-3 The transmission mechanism 57 includes a first bevel gear 571, the first bevel gear 571 is fixedly connected to the outer side of the rear rotating shaft 52, and a second bevel gear 572 that meshes with the first bevel gear 571 is fixedly connected to the outer side of the drive shaft 41.
[0029] With the above structural configuration, after the drive motor 3 starts, the drive shaft 41 begins to rotate clockwise / counterclockwise around its own axis, and the second bevel gear 572 fixed on its outer side rotates synchronously. The second bevel gear 572 meshes with the first bevel gear 571 on the rear rotating shaft 52 at a 90° angle, converting the vertical rotation of the drive shaft 41 into the horizontal rotation of the rear rotating shaft 52. By controlling the gear ratio (e.g., 1:1 or a gear ratio) of the bevel gears, the synchronicity or proportional relationship between the rotation speed of the rotating shaft 52 and the drive shaft 41 is controlled. When the rear rotating shaft 52 rotates, it drives the front rotating shaft 52. The synchronous rotation ensures that the movement phases of the two discs 53 and the fixed column 54 are consistent. The rotating shaft 52 drives the disc 53 to rotate, and the fixed column 54 moves in a circular motion with the disc 53. One end of the connecting rod 55 is hinged to the fixed column 54, and the other end is rigidly connected to the main rod 56, converting the circular motion into the vertical reciprocating linear motion of the main rod 56. While the main rod 56 is vertically rising and falling, the rotation of the drive shaft 41 drives the horizontal plate 42, the base plate 51 and the main rod 56 to revolve around the axis of the drive shaft 41, so that the stirring rod 6 has a spiral trajectory of rotation (rising and falling) + revolution (rotation) at the same time.
[0030] Reference Figure 1-3 Among them, the eight stirring rods consist of four long rods and four short rods;
[0031] With the above structural setup, the difference in rotation radius between the long rod and the short rod creates a two-way vortex. The long rod pushes the raw material to diffuse outward, while the short rod forms a centripetal backflow in the middle, accelerating the interaction and penetration of components in different regions.
[0032] Reference Figure 1-3 Two handles 7 are fixedly connected to the top of the top cover 2;
[0033] With the above structural design, the handle 7 provides a lever fulcrum, allowing workers to apply force by holding it with both hands, which greatly reduces the torque required when screwing the top cover 2, avoiding the risk of slippage and hand injury caused by the top cover 2 being too tight or sticking. The symmetrical layout of the two handles 7 allows the operator to apply force simultaneously, ensuring that the top cover 2 is screwed in / out vertically along the thread axis, preventing thread wear or sealing failure caused by uneven force.
