Description

Technical Field

[0001] This utility model relates to the technical field of grinding wheel processing, specifically to an abrasive feeder for producing grinding wheels. Background Technology

[0002] A grinding wheel is a bonded abrasive tool that binds ordinary abrasive into a certain shape and has a certain strength using a bonding agent. It is generally composed of abrasive, bonding agent, and pores. These three parts are often referred to as the three elements of a bonded abrasive tool. In the grinding wheel processing, it is necessary to quantitatively feed the abrasive. However, current quantitative feeding devices have problems such as quantitative errors and easy clogging.

[0003] A patent publication number CN216917804U was found, entitled "A Novel Feeding Device," which specifically discloses a novel feeding device. The device includes a fixedly mounted material tray for temporarily storing materials. A support is fixedly mounted on the edge of the tray, and a motor is fixedly connected to the support. The output end of the motor is connected to a rotating shaft. A material-pushing blade for moving materials within the tray is mounted on the outer surface of the rotating shaft. Several material-leaking holes are provided on the base of the tray for material to fall through. An upper funnel is located below the material-leaking holes, and a lower funnel is located below the upper funnel for receiving materials falling from it. A fixing frame is fixedly mounted at the lower end of the tray. A cylinder A is connected to the lower end of the fixing frame via a pin. The other end of cylinder A is connected to a swing head via a pin. A sealing plate for blocking the material-leaking holes is fixedly connected to the swing head.

[0004] Analysis of the publicly available materials shows that abrasive can be added, but the structure is too complex during the sealing process and cannot effectively prevent leakage. In addition, material blockage is easily caused in the lower funnel. Utility Model Content

Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-5 As shown: Example

[0025] An abrasive feeder for producing grinding wheels includes a feeder body 1, a motor 2 mounted on the feeder body 1, a feed plate 3 connected to the output end of the motor 2, a discharge hole 4 at the bottom of the feeder body 1, and a discharge mechanism. The discharge mechanism includes a movable plate 5 disposed in the discharge hole 4, a pull rod 9 connected to the end of the movable plate 5, a sealing plate 10 connected to the pull rod 9, and a telescopic rod of a cylinder 6 connected to the movable plate 5. An arch-breaking mechanism includes a connecting frame 7 disposed on the lower end face of the feeder body 1, a funnel 8 connected to the connecting frame 7, an arch-breaking device 11 disposed inside the funnel 8, and a support 12 connected to the arch-breaking device 11.

[0026] In this embodiment, the feeder body 1 is fixed on the grinding wheel production line. The mold for transporting grinding wheels is on the production line. A motor 2 is installed on the feeder body 1. The motor 2 drives the material feeding plate 3 to rotate through the shaft. The material feeding plate 3 can evenly disperse the material and also achieve the effect of filling the material in the material leakage hole 4. In addition, in order to prevent excess material from falling during the feeding process, a moving plate 5 is installed in the material leakage hole 4. The moving plate 5 can move under the action of the cylinder 6. A pull rod 9 is fixedly connected to the moving plate 5. A sealing plate 10 is connected through the pull rod 9. When feeding, the sealing plate 10 blocks the material leakage hole 4. After the material is fed, the sealing plate 10 returns to its original position under the action of the cylinder 6 and continues to fill the abrasive into the material leakage hole 4. Example

[0027] The end of the movable plate 5 is a ramp structure, the pull rod 9 is set on the ramp and is set vertically, and the upper end of the pull rod 9 is fixedly connected to the sealing plate 10.

[0028] Unlike the above embodiments, in this embodiment, in order to ensure complete abrasive addition in the leakage hole 4, the end of the moving plate 5 is set as a ramp structure, and the pull rod 9 is set on the ramp and fixedly connected. The pull rod 9 is set vertically, and the sealing plate 10 is fixed at the upper end of the pull rod 9 for pulling the sealing plate 10 to move horizontally. Example

[0029] The blocking plate 10 is inserted into the bottom of the feeder body 1, and a position is reserved for the horizontal movement of the blocking plate 10.

[0030] Unlike the above embodiments, in this embodiment, a hole with the same shape and thickness as the sealing plate 10 is reserved at the bottom of the dispenser body 1, and the end of the sealing plate 10 is designed with a ramp structure to avoid obstructing the sealing plate 10 when it returns to its original position. Example

[0031] The upper surface of the sealing plate 10 is flush with the bottom surface of the feeder body 1.

[0032] Unlike the above embodiments, in this embodiment, the upper surface of the sealing plate 10 is flush with the bottom of the feeder body 1 to avoid material accumulation there. Example

[0033] The arch breaker 11 has a conical structure with the tip pointing upwards, and there is a gap between the outer side of the arch breaker 11 and the inner side of the funnel 8.

[0034] Unlike the above embodiments, in this embodiment, in order to avoid the formation of an arch at the bottom of the funnel 8 during the abrasive feeding process, an arch breaker 11 is provided in the funnel 8. The tip of the arch breaker 11 faces upward to facilitate arch breaking. Example

[0035] The support 12 is rod-shaped, with one end connected to the inner side of the funnel 8 and the other end connected to the outer side of the arch breaker 11, for fixing and supporting the arch breaker 11.

[0036] Unlike the above embodiments, in this embodiment, the bracket 12 is used to support the arch breaker 11.

[0037] The working method (or working principle) of this utility model:

[0038] In operation, the feeder body 1 is fixed on the grinding wheel production line. Pre-mixed abrasive is poured into the feeder body 1. After starting the motor 2, the feeding plate 3 rotates under the action of the motor 2. The rotation of the feeding plate 3 completely fills the material in the discharge hole 4, achieving a quantitative effect. By retracting the cylinder 6, the extension rod of the cylinder 6 drives the moving plate 5 to move horizontally. At this time, the empty space between the feeding plates 3 rotates to above the discharge hole 4. Simultaneously, as the material falls from the discharge hole 4, the sealing plate 10 seals the discharge hole 4. After the material has completely fallen, by extending the cylinder 6, the moving plate 5 seals the lower end of the discharge hole 4, and the sealing plate 10 moves away from the upper end of the discharge hole 4. After the feeding plate 3 rotates, the discharge hole 4 is filled with abrasive again.

[0039] In this utility model, unless otherwise explicitly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
