Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel forming technology, specifically relating to a multi-cavity rotary scraping mechanism. Background Technology

[0002] Multi-station automatic grinding wheel forming machines are widely used in the field of resin sheet grinding wheel forming due to their relatively low requirements for forming materials and production environment, strong adaptability, high production efficiency, convenient operation, and stable product quality. Since multi-station grinding wheel forming machines serve abrasive products and operate for long periods with fast production cycles, wear and tear on machine parts is inevitable. Currently, the scrapers in the scraping devices of multi-station grinding wheel forming machines are directly connected to the scraper seat with fasteners, and there are few adjustment points. When wear causes slight inaccuracies in mold positioning, it will lead to interference between the scraper and the mold ring, or gaps between the scraper and the mold ring, or interference between the scraper and the mandrel, or the scraper not being tangent to the mandrel. This will cause the equipment to malfunction, or the material near the mold ring and mandrel may not be scraped evenly, resulting in uneven density. Frequent adjustments are required to resolve this, reducing work efficiency. Utility Model Content

[0003] This utility model provides a multi-cavity rotary scraping mechanism, which uses an adjustable scraper assembly to change the original fixed installation method, improves the applicability of the scraper, and the scraper corresponds one-to-one with the rotating mold.

[0004] The technical solution adopted in this utility model is as follows: A multi-cavity rotary scraping mechanism includes a scraping structure and a mold rotation structure. The scraping structure is positioned above the mold rotation structure, which has at least two molds. The scraping structure includes a scraping base plate, a scraping telescopic power component, and an adjustable scraping plate assembly. The telescopic part of the scraping telescopic power component is connected to the scraping base plate and drives the scraping base plate to move up and down. An adjustable scraping plate assembly is mounted on the scraping base plate, and each adjustable scraping plate assembly corresponds to one mold. The adjustable scraping plate assembly changes the original fixed scraping plate into an adjustable one, and, driven by the scraping telescopic power component, cooperates with the rotating mold to scrape the material on the mold.

[0005] In a preferred embodiment of this invention, the adjustable scraper assembly includes a scraper fixing base plate, a scraper moving plate, a scraper fine-tuning height adjustment component, and a scraper. The scraper fixing base plate is mounted on the scraper base plate, and the scraper fine-tuning height adjustment component is mounted on the scraper fixing base plate. The scraper fine-tuning height adjustment component is connected to the scraper moving plate and drives the scraper moving plate to move up and down. The scraper moving plate is detachably mounted with the scraper. The scraper fine-tuning height adjustment component can change the vertical installation height of the scraper, and the installation position between the scraper and the scraper moving plate can also be changed.

[0006] In a preferred embodiment of this invention, the scraper height adjustment component is an adjusting bolt. The scraper fixing base plate has a threaded hole, and the adjusting bolt passes through and is threadedly connected to the threaded hole. The lower end of the adjusting bolt is fixedly connected to the scraper moving plate. A guide post is provided between the scraper fixing base plate and the scraper moving plate. To facilitate rotation of the adjusting bolt, a handle is provided at the top of the adjustment plate. Rotating the handle rotates the adjusting bolt. Due to the two guide posts, the scraper moving plate does not rotate with the adjusting bolt, thus converting the rotation of the adjusting bolt into the up-and-down movement of the scraper moving plate, adjusting the set height of the scraper.

[0007] In a preferred embodiment of this invention, a scraper mounting seat is adjustablely installed under the scraper moving plate. The scraper mounting seat has a scraper mounting groove, and a sliding rod is installed in the scraper mounting groove. A scraper mounting block is slidably mounted on the sliding rod, and the scraper is detachably mounted on the scraper mounting block. The scraper is positioned radially along the mold. The installation position between the scraper mounting seat and the scraper moving plate is adjustable. The scraper mounting block can slide on the sliding rod, and the sliding rod and the scraper are parallel to each other, i.e., both are radially aligned with the mold. The scraper mounting block can change the position of the scraper radially in the mold.

[0008] As a preferred embodiment of this utility model, at least two sliding rods are provided in the scraper mounting groove. The two sliding rods can prevent the scraper mounting block from rotating.

[0009] As a preferred embodiment of this utility model, the scraper telescopic power component is a telescopic cylinder. The piston rod of the telescopic cylinder passes through the cylinder body fixing plate and is fixedly connected to the scraper base plate. The cylinder body fixing plate is installed on the frame of the molding machine.

[0010] In a preferred embodiment of this invention, a guide post is installed between the cylinder fixing plate and the scraper plate. The guide post ensures the straightness of the scraper plate during its vertical movement, preventing skewing and affecting the scraper.

[0011] In a preferred embodiment of this invention, the mold rotation structure includes a rotary motor, a rotary drive wheel, a mold mounting plate, a mold shaft, a mold, and a rotary driven wheel. The mold shaft is mounted on the mold mounting plate via bearings, and a mold is mounted on the top of the mold shaft. A rotary driven wheel is mounted on the end of the mold shaft that passes through the mold mounting plate. The output shaft of the rotary motor is connected to the rotary drive wheel, and the rotary drive wheel is connected to each rotary driven wheel via a transmission connection. One rotary motor can simultaneously drive several molds to rotate, improving the efficiency of grinding wheel manufacturing.

[0012] In a preferred embodiment of this utility model, the rotating driving wheel is a driving gear, and the rotating driven wheel is a driven gear; each rotating driven wheel is arranged around the rotating driving wheel and simultaneously meshes with the rotating driving wheel.

[0013] This invention changes the original method of directly fixing the scraper blade, and sets it into a structure that can adjust the installation position and installation height, thereby improving the applicability of the scraper blade. It also uses a rotary motor to drive multiple molds to work with the scraper blade to manufacture multiple products at once, thus improving work efficiency. Attached Figure Description

[0022] 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.

[0023] Example: Example: A multi-cavity rotary scraping mechanism, such as Figure 1 As shown, it includes a scraping structure and a mold rotation structure; as Figure 5-7As shown, the mold rotation structure includes a rotary motor 21, a rotary drive wheel 22, a mold mounting plate 23, a mold shaft 24, a mold 25, and a rotary driven wheel 26. The rotary motor 21 is mounted on a motor mounting plate, and its output shaft passes through the motor mounting plate and connects to the rotary drive wheel 22, driving the rotary drive wheel 22 to rotate. The mold mounting plate 23 is located above the motor mounting plate, forming a transmission power cavity between them. Three mold shafts 24 are mounted on the mold mounting plate 23, and the end of each mold shaft 24 is mounted at a rotation clearance hole in the mold mounting plate 23 via a bearing. A rotary driven wheel 26 is installed at the position where the mold shaft 24 extends into the transmission power cavity. The three rotary driven wheels 26 are arranged around the rotary drive wheel 22, and all three rotary driven wheels 26 are simultaneously connected to the rotary drive wheel 22 in a transmission manner. In this embodiment, both the rotary drive wheel and the rotary driven wheel use gears.

[0024] Each mold shaft 24 has a mold 25 mounted on its top; a rotary motor drives several molds to rotate simultaneously, improving the efficiency of grinding wheel production.

[0025] A scraping structure is provided above the rotating mold structure, such as... Figure 2-3 As shown, the scraping structure includes a scraping base plate 11, a scraping telescopic power component 12, and an adjustable scraping plate assembly. The scraping telescopic power component 12 is a telescopic cylinder. The piston rod of the telescopic cylinder passes through the cylinder body fixing plate 121 and is fixedly connected to the scraping base plate 11. The cylinder body fixing plate 121 is installed on the frame of the molding machine.

[0026] The telescopic part of the scraper telescopic power component 12 is connected to the scraper base plate 11 and drives the scraper base plate 11 to move up and down. In order to ensure the straightness of the up and down movement and avoid deflection, a guide post 3 is installed between the cylinder fixing plate 121 and the scraper base plate 11. In this embodiment, the lower end of the guide post is fixed on the scraper base plate, the guide post passes through the cylinder fixing plate 121 and protrudes, and an anti-detachment block is provided on the guide post.

[0027] The scraper telescopic power component 12 is fixedly connected to the center of the scraper substrate. Three sets of adjustable scraper plate assemblies are symmetrically arranged around the center on the scraper substrate 11, and each adjustable scraper plate assembly corresponds to a mold.

[0028] like Figure 2-4As shown, each adjustable scraper assembly includes a scraper fixing base plate 13, a scraper moving plate 14, a scraper fine-tuning height component 15, a scraper mounting base 16, and a scraper 17. The scraper fine-tuning height component 15 uses an adjusting bolt. The scraper fixing base plate 13 is mounted on the scraper base plate 11 by bolts. The scraper fixing base plate 13 is provided with a threaded hole. The adjusting bolt passes through the threaded hole and is threadedly connected to the threaded hole. The lower end of the adjusting bolt is fixedly connected to the scraper moving plate 14. A guide post 3 is provided between the scraper fixing base plate 13 and the scraper moving plate 14. The lower end of the guide post is fixed to the scraper moving plate, and the upper end of the guide post protrudes through the scraper fixing base plate 13. An anti-detachment block is provided on the guide post.

[0029] To facilitate the rotation of the adjusting bolt, a handle is provided at the top of the adjustment. Rotating the handle will rotate the adjusting bolt. Due to the setting of the two guide posts, the scraper moving plate 14 will not rotate with the adjusting bolt, thus converting the rotation of the adjusting bolt into the up and down movement of the scraper moving plate, thereby adjusting the setting height of the scraper.

[0030] The scraper mounting plate 14 is adjustablely mounted with a scraper mounting seat 16. In this embodiment, it is fixed with screws and different mounting positions are set. The scraper mounting seat 16 has a scraper mounting groove 161 at the bottom. Two sliding rods 18 are installed in the scraper mounting groove 161. The scraper mounting block 19 is slidably mounted on the sliding rods 18. The scraper mounting block 19 has a scraper mounting groove at the bottom. The scraper 17 is installed in the scraper mounting groove and is tightened by a lateral locking pin, so as to achieve detachable installation on the scraper mounting block 19.

[0031] The scraper 17 is set in the radial direction of the mold, and the slide bar is parallel to the setting direction of the scraper.

[0032] The installation position between the scraper mounting base 16 and the scraper moving plate can be adjusted. The scraper mounting block can slide on the slide rod, and the slide rod and the scraper are set in the same direction, i.e., both are radial to the mold. The scraper mounting block can change the position of the scraper in the radial direction of the mold.
