Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel production, in particular to a diamond cylindrical grinding wheel batching device. Background Art

[0002] Grinding wheel, also known as bonded abrasive, is a bonded abrasive with a certain shape and strength. It is generally composed of abrasive, bond and pores. These three parts are often called the three elements of bonded abrasive. Grinding wheel is the most widely used abrasive. It rotates at high speed when used, and can be used for rough grinding, semi-finishing grinding and fine grinding of the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces, as well as slotting and cutting. For example, the diamond cylindrical grinding wheel is made of abrasives such as corundum, silicon carbide and boron nitride. The abrasives need to be mixed and batched through a batching device during manufacturing.

[0003] At present, a Chinese patent with the announcement number CN213314399U discloses a grinding wheel production batching device, including an installation box, in which a feeding assembly and a stirring assembly are arranged in sequence from top to bottom. Among them, the feeding assembly includes a feeding roller engaged between two fixed plates, and a feeding trough is provided on the side wall of the feeding roller. When in use, driven by the second servo motor, the feeding trough can be engaged between the two fixed plates to receive the abrasive; after the loading is completed, the second servo motor can also drive the feeding trough to rotate downward to pour the abrasive into the stirring assembly for stirring. In addition, a limit plate that can be ejected by a cylinder is also provided in the feeding trough, and the ejection of the limit plate can prevent the abrasive from sticking to the feeding trough. However, the use of the cylinder will cause the addition of a driving source, which is not conducive to reducing the system complexity of the device. Utility Model Content

[0007] The driving board is connected with a second reset member.

[0008] The material receiving port is connected to the abrasive metering equipment through a pipeline.

[0009] The first restoring member and the second restoring member are both springs.

[0010] The material receiving opening is arranged with several parts around the rotating roller.

DETAILED DESCRIPTION

[0016] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0017] like Figure 1As shown, a diamond cylindrical grinding wheel batching device includes a housing 1, in which a feeding assembly 2 and a stirring assembly 3 are sequentially arranged from top to bottom. Among them, the stirring assembly 3 can be selected as a stirring mechanism commonly used in the prior art for stirring the grinding wheel abrasive batching operation, which will not be described in detail in this embodiment. The feeding assembly 2 includes a receiving plate 4 and a rotating roller 5 connected to the receiving plate 4. For example, the bottom surface of the receiving plate 4 is constructed with an arc surface 12 that fits the outer wall of the rotating roller 5, and the receiving plate 4 is also constructed with a receiving port 6 connected to the arc surface 12. Correspondingly, a feeding trough 7 is opened on the side wall of the rotating roller 5, and a driving member for driving the rotating roller 5 to rotate is also provided on the housing 1.

[0018] In some embodiments, the receiving port 6 is provided with a plurality of Figure 1 In the figure, a preferred example in which there are three receiving ports 6 is preferably shown, for example, the three receiving ports 6 can be used to receive three abrasives, namely corundum, silicon carbide and boron nitride, respectively. Therefore, the rotating roller 5 can have a receiving position and a discharging position selected by the driving rotation of the driving member. For example, there can be multiple receiving positions, for example, the rotating roller 5 can make the discharging trough 7 relative to different receiving ports 6 at different receiving positions, so as to realize the acceptance of different abrasives. In a possible example, different abrasives can be loaded in the discharging trough 7 by layering, which will enable the abrasive to obtain a pre-mixed effect. For example, the driving member can drive the rotating roller 5 to reciprocate in the arc surface 12, so as to realize the oscillating mixing of the abrasive in the discharging trough 7. Preferably, the arc surface 12 is also constructed to have a mixing section 13, and the discharging trough 7 can reciprocate in the interval of the mixing section 13 without causing leakage of the abrasive.

[0019] For example, each material receiving port 6 can be connected to an abrasive metering device through a pipeline. The abrasive metering device is a prior art and will not be described in detail in this example. The abrasive metering device can realize a more accurate material feeding operation with different abrasive ratios, making the ratio operation more accurate.

[0020] In order to prevent the abrasive in the feeding trough 7 from sticking to the material at the feeding position, in the present disclosure, a push plate 8 is sealed and slidably connected in the feeding trough 7, a driving cavity is also provided in the rotating roller 5, and the driving cavity is connected to the feeding trough 7. In addition, a driving plate 10 is sealed and slidably connected in the driving cavity.

[0021] In some embodiments, the push plate 8 and the drive plate 10 are respectively connected to a reset member 1 9 and a reset member 2 11 , for example, both reset members can preferably be springs.

[0022] Therefore, when batching, the rotating roller 5 realizes the receiving of the abrasive by the material discharge trough 7 at the material receiving position; after the loading is completed, the rotating roller 5 rotates from the material receiving position to the material discharge position, during which the driving plate 10 in the driving cavity slides under the action of gravity, thereby generating positive pressure on the side of the material discharge trough 7, thereby pushing the push plate 8 to slide in the material discharge trough 7 to complete the material pushing action, and finally preventing the abrasive from sticking to the material discharge trough 7. It can be imagined that under the action of the two reset members, at the material receiving position, the push plate 8 is easier to return downward to the initial position and reopen the material discharge trough 7, and the driving plate 10 is also easier to return to the initial position, so as to be used for the next material discharge operation to drive the push plate 8.

[0023] It can be understood that, compared with the gravity drop of the push plate 8 alone, the push plate 8 can obtain a greater driving force through the cooperation between the drive plate 10 and the drive cavity to achieve the scraping action on the material trough 7. In a preferred example, the cross-sectional area of ​​the drive cavity is configured to be larger than the cross-sectional area of ​​the material trough 7, so that the sliding of the drive plate 10 in the drive cavity can generate a greater positive pressure to push the push plate 8 to complete the above-mentioned pushing action.

[0024] In some embodiments, the reset member 11 is preferably configured as a damping spring, for example, the damping spring is a spring device with a damper. Therefore, the rotating roller 5 can also have a scraping position selected by the driving rotation of the driving member. For example, after the above-mentioned unloading action is completed, the driving member can drive the rotating roller 5 to rotate upward rapidly. At this time, under the damping force of the reset member 11, the push plate 8 will gradually fall to engage with the outer wall of the rotating roller 5, and the unloading trough 7 will gradually engage with the arc surface 12. In this way, the receiving plate 4 can scrape the abrasive adhering to the end face of the push plate 8 to the stirring assembly 3 for stirring, thereby ensuring the accuracy of the batching operation.

[0025] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
