DETAILED DESCRIPTION

[0032] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0033] Example 1

[0034] As shown in Figure 2 and Figure 3 , the present embodiment provides a grinding wheel forming material scraping device, which comprises a processing platform 1 and a conveying channel 101 opened on the processing platform 1, and a scraping assembly 2 for scraping the surface of the forming material in the mold a is arranged on the processing platform 1; the mold a is of an integrated structure and comprises a circular bottom, an annular side portion connected to the circular bottom, and a cylindrical portion connected to the middle position of the circular bottom; wherein the inner annular surface of the annular side portion and the upper surface of the circular bottom directly contact with the forming material; the molds a in the conveying channel 101 are arranged in sequence and move intermittently along the direction of the conveying channel 101 under the action of external force, and the mold a is fitted with the side wall of the conveying channel 101 to ensure that the mold a does not deviate; when the mold a is in a stationary state, the external material conveying device conveys the forming material into the mold a, and the scraping assembly 2 scrapes the surface of the forming material in the mold a.

[0035] As shown in Figure 3 and Figure 5 , the scraping assembly 2 comprises a vertical sleeve 201 which is matched with the cylindrical portion of the mold a, and in operation, the sleeve 201 is sleeved on the cylindrical portion of the mold a; the sleeve 201 can rotate relative to the cylindrical portion of the mold a and can be lifted and lowered relative to the cylindrical portion of the mold a; the bottom surface of the sleeve 201 is provided with a horizontal first scraping strip 202, and the bottom surface of the first scraping strip 202 is slidingly provided with a second scraping strip 203; the first scraping strip 202 is arranged along the radial direction of the mold a, and the second scraping strip 203 is parallel to the first scraping strip 202, and the sliding direction of the second scraping strip 203 is parallel to the first scraping strip 202; the bottom surfaces of the first scraping strip 202 and the second scraping strip 203 are flush, and the bottom surface of the first scraping strip 202 is provided with an accommodating groove 204 matched with the second scraping strip 203.

[0036] In particular, the sleeve 201, the first scraping strip 202 and the second scraping strip 203 are lowered to the bottom of the mold a in advance, and as the external material conveying device conveys the molding material into the mold a, the molding material in the mold a is accumulated more and more, and the surface of the molding material is gradually lifted. After the external material conveying device pauses to convey the molding material into the mold a, the sleeve 201, the first scraping strip 202 and the second scraping strip 203 are first lifted until the bottom surface of the first scraping strip 202 and the second scraping strip 203 is lifted to a predetermined height, and then the sleeve 201, the first scraping strip 202 and the second scraping strip 203 are rotated to scrape the surface of the molding material by the first scraping strip 202 and the second scraping strip 203 (the end of the first scraping strip 202 is attached to the outer sidewall of the cylindrical part of the mold a). Since the inner sidewall of the mold a is not a vertical annular surface, but has ups and downs, the second scraping strip 203 will slide synchronously under the action of an external force during the lifting of the first scraping strip 202 and the second scraping strip 203, so that the end of the second scraping strip 203 is always attached to the inner sidewall of the mold a, that is, the first scraping strip 202 and the second scraping strip 203 can cover the cross section of the mold a at any height in the mold a when they are rotated.

[0037] It should be noted that the amount of molding material conveyed by the external material conveying device into the mold a each time is a predetermined amount, and the amount of molding material conveyed by the material conveying device into the mold a each time is different, so that after each conveying is completed, the molding material in the mold a is lifted to a consistent height while ensuring that the surface is level. In addition, the driving mode of the second scraping strip 203 includes but is not limited to electric driving.

[0038] As shown in Figure 2 , two electric telescopic plates 3 are vertically installed on the processing platform 1 on both sides of the conveying channel 101, and the telescopic segments of the two electric telescopic plates 3 are jointly installed with a horizontal lifting platform 4, the lifting platform 4 is provided with a discharging hole penetrating through the lifting platform 4, and the sleeve 201 is rotatably installed on the bottom surface of the lifting platform 4. The electric telescopic plate 3 drives the lifting platform 4 to lift during the telescopic process, thereby driving the sleeve 201, the first scraping strip 202 and the second scraping strip 203 to lift synchronously. The sleeve 201 drives the first scraping strip 202 and the second scraping strip 203 to rotate relative to the mold a when it rotates under the action of an external force.

[0039] As shown in Figure 3 and Figure 5 , the electric telescopic plate 3 is slidingly installed on the processing platform 1 along the conveying direction of the conveying channel 101; the first scraping strip 202 is slidingly matched with the bottom surface of the sleeve 201 along the radial direction of the sleeve 201; the edge of the bottom surface of the first scraping strip 202 close to the center of the sleeve 201 is rounded, the inner edge of the bottom surface of the sleeve 201 is rounded, a protruding part is arranged on the first scraping strip 202, and an elastic member 9 is connected between the protruding part and the sleeve 201, and a stop block 5 attached to the outer wall of the sleeve 201 is fixedly installed on the first scraping strip 202.

[0040] Specifically, if the mold a is just in position corresponding to the sleeve 201 when it is static, the sleeve 201, the first scraping strip 202 and the second scraping strip 203 will directly fit on the cylindrical part of the mold a during the descending process, and the electric telescopic plate 3 and the lifting platform 4 will not produce horizontal movement; if the axis of the cylindrical part of the mold a deviates from the axis of the sleeve 201 when it is static, the first scraping strip 202 will first contact and be extruded by the top surface of the cylindrical part of the mold a during the descending process of the sleeve 201, the first scraping strip 202 will slide horizontally under the reaction force of the mold a, the elastic member 9 will be deformed, and the stop block 5 will be separated from the outer wall of the sleeve 201; then, as the sleeve 201, the first scraping strip 202 and the second scraping strip 203 continue to descend, the inner edge of the bottom surface of the sleeve 201 contacts the top surface of the cylindrical part of the mold a, and since the mold a itself is heavy and is not easy to produce horizontal deviation, the sleeve 201 will drive the lifting platform 4 and the electric telescopic plate 3 to move horizontally along the conveying channel 101 under the reaction force of the mold a until the axis of the cylindrical part of the mold a aligns with the axis of the sleeve 201, so that the sleeve 201 can be smoothly fitted on the cylindrical part of the mold a; after the sleeve 201 is fitted on the cylindrical part of the mold a, the first scraping strip 202 is no longer subjected to the reaction force of the mold a, the elastic member 9 returns to its original state, and the first scraping strip 202 and the stop block 5 reset relative to the sleeve 201 until the stop block 5 re-adjoins the outer wall of the sleeve 201.

[0041] In summary, the horizontal position of the scraping assembly 2 in the embodiment can be self-adaptively adjusted, that is, even if the actual position of the mold a deviates from the predetermined position after the conveying is stopped, the scraping assembly 2 can normally scrape the molding material in the mold a; it should be noted that the electric telescopic plate 3 is provided with a roller which rolls with the processing platform 1 to reduce the friction therebetween and ensure that the lifting platform 4 and the electric telescopic plate 3 can produce horizontal movement under the action of the sleeve 201.

[0042] As Figure 2 and Figure 3As shown, the grinding wheel forming material leveling device in the embodiment further comprises a guide assembly 6 for horizontally guiding the second scraping strip 203, the guide assembly 6 comprises a circular ring 601 mounted on the limiting sections of the two electric telescopic plates 3 and coinciding with the axis of the sleeve 201; the circular ring 601 coincides with the axis of the sleeve 201 and can rotate relative to the sleeve 201; the electric telescopic plate 3 moves horizontally to drive the circular ring 601 to rotate synchronously; a vertical plate 602 is mounted on the circular ring 601 through a connecting arm, and a guide groove 603 is formed on the surface of the vertical plate 602; the shape of the guide groove 603 is consistent with the shape of the inner side wall of the mold a; the number of the vertical plate 602 corresponding to each first scraping strip 202 on the circular ring 601 is two, and the two vertical plates 602 are arranged on the two sides of the first scraping strip 202 respectively; a rigid rod 604 is fixedly installed on the second scraping strip 203, and a guide block 605 matched with the guide groove 603 is installed on the rigid rod 604, and the guide block 605 is in the shape of a round pin and rotates with the rigid rod 604.

[0043] Specifically, when the guide block 605 is located in the guide groove 603 and moves up and down along the guide groove 603, the guide block 605 drives the second scraping strip 203 to move synchronously through the rigid rod 604, that is, the second scraping strip 203 moves along the shape of the inner side wall of the mold a; in the embodiment, when the second scraping strip 203 descends to the position corresponding to the top of the mold a, the guide block 605 reaches the top of the guide groove 603; as the sleeve 201, the first scraping strip 202, the second scraping strip 203, the rigid rod 604 and the guide block 605 descend as a whole, the guide block 605 moves along the guide groove 603, and the second scraping strip 203 also slides synchronously relative to the first scraping strip 202, so that the end of the second scraping strip 203 always fits the inner side wall of the mold a; in the embodiment, the connecting arm and the vertical plate 602 are in a plug-in structure, and the vertical plate 602 can be replaced; for different shapes of grinding wheels, the shape of the mold a is also different, and the corresponding model of the vertical plate 602 can be selected and installed before processing.

[0044] As described above, in the embodiment, the second scraping strip 203 can be driven to slide relative to the first scraping strip 202 without an additional power source, and the end of the second scraping strip 203 can always fit the inner wall of the mold a at any height; and since the end of the second scraping strip 203 only fits the inner side wall of the mold a, no extrusion force is generated between them, thereby significantly reducing the wear of the second scraping strip 203 and the inner side wall of the mold a during rotation of the second scraping strip 203.

[0045] As Figure 2As shown, the electric telescopic plate 3 is fixedly installed with a limiting plate 607 for limiting the circular ring 601, so as to prevent the circular ring 601 from shaking and improve the stability of the circular ring 601. The limiting plate 607 is installed with a ball in rolling connection with the circular ring 601, so as to reduce the friction force suffered by the circular ring 601 and ensure smooth rotation of the circular ring 601 under a smaller external force.

[0046] As shown in Figure 3 and Figure 5 As shown, the first scraping strip 202 is slidably installed with a stabilizing frame 606 fixedly connected with the rigid rod 604, so as to reduce the shaking of the rigid rod 604. The surface of the sleeve 201 is provided with a vertical slot 205 in sliding connection with the vertical plate 602, which extends downward to the bottom surface of the sleeve 201. The top of the sleeve 201 is fixedly sleeved with a driven gear ring 7. The lifting platform 4 is installed with a motor. The output shaft of the motor is fixedly installed with a driving gear 8 in engagement with the driven gear ring 7. When the motor is started, the driving gear 8 is driven to rotate, which drives the sleeve 201, the first scraping strip 202, the second scraping strip 203, the rigid rod 604, the guide block 605 and the stabilizing frame 606 to rotate as a whole. When the second scraping strip 203 is lowered to correspond to the top position of the mold a, the guide block 605 is just at the top of the guide slot 603, and the end of the vertical plate 602 is just in the vertical slot 205. In this way, the sleeve 201 is driven to rotate, which drives the vertical plate 602, the connecting arm and the circular ring 601 to rotate synchronously. The vertical plate 602 can maintain a constant height and rotate synchronously with the second scraping strip 203, the rigid rod 604 and the guide block 605.

[0047] It should be noted that, as shown in Figure 4 the horizontal plane where the bottom surface of the limiting plate 607 is located is higher than the horizontal plane where the top surface of the mold a is located, that is, the limiting plate 607 and the vertical plate 602 will not block the mold a during horizontal conveying.

[0048] The embodiment provides a use method of the above-mentioned grinding wheel forming material scraping device, which comprises the following steps:

[0049] Step one: move the mold a to the position corresponding to the scraping assembly 2 in the conveying channel 101, start the electric telescopic plate 3, and drive the lifting platform 4, the sleeve 201, the first scraping strip 202 and the second scraping strip 203 to lower as a whole by the electric telescopic plate 3, so as to finely adjust the position of the scraping assembly 2 and make the sleeve 201 correspond to the center of the mold a.

[0050] Step two: drive the lifting platform 4, the sleeve 201, the first scraping strip 202 and the second scraping strip 203 to continue to move downward by the electric telescopic plate 3, until the first scraping strip 202 and the second scraping strip 203 are in close contact with the inner bottom surface of the mold a.

[0051] Step three: intermittently feed the molding material into the mold a through the external feeding device, and the sleeve 201 drives the first scraper 202 and the second scraper 203 to intermittently rise; when the electric telescopic plate 3 stops telescoping, the motor is started, the motor drives the driving gear 8 to rotate, the driving gear 8 drives the sleeve 201 to rotate through the driving driven gear 7, and the sleeve 201 drives the first scraper 202 and the second scraper 203 to rotate; during the rising of the second scraper 203 and the first scraper 202, the motor is in the closed state, and the second scraper 203 slides horizontally relative to the first scraper 202 to ensure that the end of the second scraper 203 is always in close contact with the inner wall of the mold a; until the first scraper 202 and the second scraper 203 move out of the mold a, that is, the scraping is finished.

[0052] Embodiment 2

[0053] In the actual production process, due to the existence of the containing groove 204, the overall bottom surface of the first scraper 202 and the second scraper 203 is not flat, and during the contact between the first scraper 202 and the second scraper 203 and the molding material, part of the molding material will enter the containing groove 204, thereby affecting the normal sliding of the second scraper 203. Based on this, the following improvements are made in this embodiment.

[0054] As shown in Figure 6 and Figure 7 , on the basis of the previous embodiment, in this embodiment, the first scraper 202 is slidably installed with a flexible material blocking piece 206, the material blocking piece 206 is strip-shaped, one end of the material blocking piece 206 is fixedly connected to the side end face of the second scraper 203 close to the sleeve 201, a part of the material blocking piece 206 is located in the containing groove 204, and the rest is located above the containing groove 204; the bottom surface of the part of the material blocking piece 206 located in the containing groove 204 is flush with the bottom surface of the second scraper 203, and the two sides of the material blocking piece 206 are in close contact with the side walls of the containing groove 204; the top surface of the containing groove 204 is provided with a sliding groove 207, and the top surface of the second scraper 203 is fixedly installed with a sliding plate 208 matched with the sliding groove 207, and the other end of the material blocking piece 206 is fixedly connected to the side surface of the sliding plate 208 away from the sleeve 201.

[0055] With Figure 7It is explained that when the second scraping strip 203 is moved to the left by the force from the rigid rod 604, the second scraping strip 203 and the sliding plate 208 are synchronously moved to the left, the bottom end of the material blocking sheet 206 is moved to the left by the pulling force of the second scraping strip 203, and the top end of the material blocking sheet 206 is also moved to the left by the pulling force; when the second scraping strip 203 is moved to the right by the force from the rigid rod 604, the second scraping strip 203 and the sliding plate 208 are synchronously moved to the left, the top end of the material blocking sheet is moved to the right by the pulling force of the sliding plate 208, and the bottom end of the material blocking sheet 206 is also moved to the right by the pulling force; it can be seen that no matter how the second scraping strip 203 slides, the material blocking sheet 206 can block the bottom of the containing groove 204 to prevent the formed material from entering the containing groove 204.

[0056] It should be noted that the material blocking sheet 206 forms two U-shaped bends in the first scraping strip 202, and the material blocking sheet 206 can be a leather material with a smooth surface or a metal material with a smooth surface; that is, the material blocking sheet 206 has elasticity, and the material blocking sheet 206 in the bent state has a tendency to restore to a flat state, so that the bent material blocking sheet 206 and the first scraping strip 202 generate a certain clamping force, which makes the first scraping strip 202 and the second scraping strip 203 maintain a relatively stable state, that is, the second scraping strip 203 does not freely slide relative to the first scraping strip 202 when not subjected to an external force, thereby ensuring that the guide block 605 can smoothly enter the guide groove 603 during the next processing after being separated from the guide groove 603.

[0057] In summary, in the embodiment, by providing the material blocking sheet 206, on the one hand, the overall bottom surface of the first scraping strip 202 and the second scraping strip 203 is ensured to be flat, and the formed material cannot enter the containing groove 204 to affect the normal sliding of the second scraping strip 203; on the other hand, the material blocking sheet 206 clamps the first scraping strip 202 to ensure that the second scraping strip 203 does not freely slide without an external force.

[0058] Embodiment 3

[0059] In actual production, due to the adhesion of the formed material, part of the formed material will adhere to the side wall of the first scraping strip 202 and the second scraping strip 203 during the scraping process, and if this part of the formed material is not removed in time, it will dry and stick to the first scraping strip 202 and the second scraping strip 203, which will seriously affect the scraping effect of the first scraping strip 202 and the second scraping strip 203; based on this, the following improvements are made in the embodiment.

[0060] As Figure 8As shown, on the basis of Embodiment 1 or Embodiment 2, in the present embodiment, the distance between the two vertical plates 602 corresponding to the same first scraping strip 202 is adapted to the width of the first scraping strip 202 and the second scraping strip 203; that is, the first scraping strip 202 and the second scraping strip 203 are attached to the surface of the vertical plate 602 during the lifting process; the vertical plate 602 is slidingly installed with a sliding rod 10 vertically penetrating the vertical plate 602, and the end face of the sliding rod 10 located in the region between the two vertical plates 602 is a hemispherical surface; the other end of the sliding rod 10 is fixedly installed with an end plate 11, and the end plate 11 is fixedly connected with the corresponding vertical plate 602 through an extension spring 12; the surface of the end plate 11 facing the corresponding vertical plate 602 is fixedly installed with a knocking block 13, and the knocking block 13 is attached to the corresponding vertical plate 602.

[0061] Specifically, during the process of conveying the molding material into the mold a by the external material conveying device, the first scraping strip 202 and the second scraping strip 203 are not rotated, at this time, the lifting platform 4, the sleeve 201, the first scraping strip 202 and the second scraping strip 203 are driven by the electric telescopic plate 3 to rise integrally until the first scraping strip 202 and the second scraping strip 203 are separated from the horizontal range covered by the mold a and rise to the horizontal range covered by the vertical plate 602; during the above process, since the distance between the two vertical plates 602 is matched with the width of the first scraping strip 202 and the second scraping strip 203, the molding material adhered to the side wall of the first scraping strip 202 and the second scraping strip 203 will contact the bottom surface of the vertical plate 602 and be scraped off from the side wall of the first scraping strip 202 and the second scraping strip 203 by the vertical plate 602, the molding material originally adhered to the side wall of the first scraping strip 202 and the second scraping strip 203 is transferred to the bottom surface of the vertical plate 602, part of the molding material will fall into the mold a under the action of gravity, but a small amount of molding material will still adhere to the bottom surface of the vertical plate 602; as the lifting platform 4, the sleeve 201, the first scraping strip 202 and the second scraping strip 203 continue to rise driven by the electric telescopic plate 3, the first scraping strip 202 will be attached to the sliding rod 10 and push the sliding rod 10 to overcome the elastic force of the telescopic spring 12, when the sliding rod 10 moves, the end plate 11 drives the knocking block 13 to separate from the vertical plate 602, and the telescopic spring 12 is stretched; after the first scraping strip 202 is separated from the sliding rod 10, the telescopic spring 12 restores and drives the sliding rod 10 to reset, the sliding rod 10 drives the end plate 11 to reset, and the knocking block 13 resets and reattaches to the vertical plate 602 during the resetting process; then, as long as the lifting platform 4, the sleeve 201, the first scraping strip 202 and the second scraping strip 203 rise integrally at a fast speed driven by the electric telescopic plate 3, the telescopic spring 12 will drive the sliding rod 10, the end plate 11 and the knocking block 13 to reset rapidly during the restoring process (it can be understood that the stretched telescopic spring 12 is released rapidly), the knocking block 13 will knock the vertical plate 602, and the vertical plate 602 will vibrate to shake the small amount of molding material adhered to the bottom surface of the vertical plate 602 and fall into the mold a; when the external material conveying device pauses to convey the molding material into the mold a, the lifting platform 4, the sleeve 201, the first scraping strip 202 and the second scraping strip 203 integrally descend driven by the electric telescopic plate 3 until the first scraping strip 202 and the second scraping strip 203 descend to a predetermined height, and the knocking block 13 knocks the vertical plate 602 again during the descending process of the second scraping strip 203.

[0062] In summary, the vertical plate 602 in the embodiment plays a role of providing guidance for the second scraping strip 203 on the one hand, and plays a role of scraping the molding material adhered to the first scraping strip 202 and the second scraping strip 203 on the other hand, and the knocking of the knocking block 13 to the vertical plate 602 is realized through the rising and falling of the first scraping strip 202 and the second scraping strip 203, which ensures that the molding material can fall back into the mold a.

[0063] The foregoing merely illustrates some exemplary embodiments of the application, and it will be appreciated that those skilled in the art will be able to devise various modifications without departing from the spirit and scope of the application. The appended drawings and description are illustrative only, and are not intended to be limiting.
