Abstract
Description
Technical Field
[0001] This utility model relates to the field of metering and sand control, specifically a metering and sand control device for grinding wheel forming. Background Technology
[0002] A grinding wheel is a bonded abrasive tool made by bonding ordinary abrasive grains into a specific shape and giving it a certain strength using a bonding agent. In existing technologies, grinding wheel forming involves a series of processes, including material preparation, spreading, heating, and pressing, all completed on a continuous production line. Because the edges of grinding wheels are typically prone to wear during use, automated production lines require different materials to be applied to the center and edges of the forming disc to increase the edge strength of the formed wheel.
[0003] Chinese Patent CN107953277A discloses a double-feeding machine for grinding wheel forming, including a material screening device, a precise metering device, an automatic control device, and a machine body fixing device. The material screening outlet is connected to the precise metering device. The precise metering device includes a feeder and a weighing sensor. The feeder is located on the top of the weighing sensor. The materials for forming the edge of the grinding wheel and the materials for forming the middle part of the grinding wheel are respectively fed through the left and right screen frames of the material screening device and then enter the outlet corresponding to the left and right precise feeding mechanisms of the forming disc edge and the middle part of the grinding wheel station. When the weight of the material in the feeder of the precise feeding mechanism reaches the set value, the weighing sensor feeds the signal back to the automatic control system. The automatic control system controls the cylinder to drive the screen frame outlet baffle to close and the feeder outlet baffle to open, so that the material is fed to the designated position of the forming disc, thus efficiently and intelligently completing the feeding of the grinding wheel edge and the middle part.
[0004] In actual use, the feeding device of the above-mentioned patent generally uses a weighing sensor to control the sand output. However, if the sand particles are small, they may enter the weighing sensor through gaps, affecting the accuracy of the weighing sensor. Utility Model Content
[0005] The purpose of this invention is to provide a metering and sand control device for grinding wheel forming. A baffle is installed on a fixed base plate, dividing the material discharge gap between the fixed base plate and the connecting plate into multiple material discharge channels. A hydraulic cylinder is installed at the lower end of the connecting plate, and a baffle block is installed on the movable end of the hydraulic cylinder. Two sets of baffle blocks and hydraulic cylinders are installed at opposite ends of the baffle. When the worker pours sand into the fixed base plate, the hydraulic cylinder at the end of the baffle closest to the material discharge plate extends the baffle block to contact the fixed base plate, blocking the sand within the material discharge channels. As sand continues to be poured in until the channels are full, the hydraulic cylinder at the other end extends the baffle block to block the inlet of the material discharge channel. Then, the baffle block at one end of the material discharge plate opens, and the sand is discharged from the material discharge plate. In this way, the amount of sand injected each time is quantitative, and the worker only needs to calculate the volume of the material discharge channel to determine the amount of material discharged each time, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a metering and sand control device for grinding wheel forming, comprising a fixed base plate, a baffle plate provided on the fixed base plate, a material discharge slide provided between the baffle plates, and a connecting plate provided on the fixed base plate. A hydraulic cylinder is provided at the lower end of the connecting plate, a material stop block is provided on the movable end of the hydraulic cylinder, second side baffle plates are provided on both sides of the fixed base plate, a feeding plate is provided at one end of the fixed base plate, and a material discharge plate is provided at the end of the fixed base plate away from the feeding plate. Second bolt holes are provided on the second side baffle plates, and first bolt holes are provided on the connecting plate at the corresponding positions of the second bolt holes.
[0007] Preferably, a bolt is provided in the first bolt hole.
[0008] Preferably, the feed plate has a rear end baffle at the end away from the fixed base plate, and the rear end baffle is welded to the feed plate.
[0009] Preferably, the feeding plate is provided with a first side baffle.
[0010] Preferably, a support column is provided at the lower end of the fixed base plate, and the support column is welded to the fixed base plate.
[0011] Preferably, the lower end of the support column is provided with a ground contact base, and the ground contact base is welded to the support column.
[0012] Preferably, the ground contact base is provided with a fixing plate.
[0013] Preferably, the fixing plate has a slot.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention features a baffle plate on a fixed base plate, which divides the material discharge gap between the fixed base plate and the connecting plate into multiple material discharge channels. A hydraulic cylinder is located at the lower end of the connecting plate, and a baffle block is installed on the movable end of the hydraulic cylinder. Two sets of baffle blocks and hydraulic cylinders are arranged at opposite ends of the baffle plate. When workers pour gravel onto the fixed base plate, the hydraulic cylinder located at the end of the baffle plate closest to the material discharge plate drives the baffle block to extend and contact the fixed base plate, blocking the gravel within the material discharge channels. Gravel is then continuously poured in until the channels are filled. The hydraulic cylinder at the other end of the discharge chute drives the baffle block to extend and block the feed inlet of the discharge chute. Then the baffle block at one end of the discharge plate opens, and the sand and gravel are discharged from the discharge plate. In this way, the amount of sand and gravel injected each time is fixed. The staff only needs to calculate the volume of the discharge chute to get the amount of material discharged each time. This effectively avoids the problem that existing feeding devices generally use weighing sensors to control the amount of sand discharged. However, small sand particles may enter the weighing sensor through gaps, affecting the accuracy of the weighing sensor. Attached Figure Description

[0022] To address the problem in existing technologies where the sand output dosage is typically controlled using a weighing sensor, but small sand particles may enter the weighing sensor through gaps, affecting its accuracy, this embodiment provides the following technical solution:

[0024] In this embodiment, please refer to Figures 1-4 A baffle 5 is installed on the fixed base plate 3, which divides the material discharge gap between the fixed base plate 3 and the connecting plate 11 into multiple material discharge channels 4. A hydraulic cylinder 12 is installed at the lower end of the connecting plate 11, and a baffle block 13 is installed on the movable end of the hydraulic cylinder 12. Two sets of baffle blocks 13 and hydraulic cylinders 12 are installed at the two ends of the baffle 5 respectively. When the worker pours sand and gravel onto the fixed base plate 3, the hydraulic cylinder 12 located at the end of the baffle 5 near the material discharge plate 6 drives the baffle block 13 to extend and contact the fixed base plate 3, blocking the sand and gravel in the material discharge channel 4. Then, as the sand and gravel continue to be injected until the material discharge channel 4 is filled, the hydraulic cylinder 12 at the other end drives the baffle block 13 to extend and block the inlet of the material discharge channel 4. Then the baffle block 13 at the end of the material discharge plate 6 opens, and the sand and gravel are discharged from the material discharge plate 6. In this way, the amount of sand and gravel injected each time is fixed, and the worker only needs to calculate the volume of the material discharge channel 4 to obtain the amount of material discharged each time.

A hydraulic cylinder 12 is set at the lower end of the connecting plate 11, and a baffle block 13 is set on the movable end of the hydraulic cylinder 12. Two sets of baffle blocks 13 and hydraulic cylinders 12 are set at the two ends of the baffle 5 respectively. When the worker pours sand and gravel into the fixed base plate 3, the hydraulic cylinder 12 at the end of the baffle 5 near the material discharge plate 6 drives the baffle block 13 to extend and contact the fixed base plate 3, blocking the sand and gravel in the material discharge channel 4. Then, as the sand and gravel continue to be poured in until the material discharge channel 4 is filled, the hydraulic cylinder 12 at the other end drives the baffle block 13 to extend and block the inlet of the material discharge channel 4. Then the baffle block 13 at the end of the material discharge plate 6 opens, and the sand and gravel are discharged from the material discharge plate 6. In this way, the amount of sand and gravel injected each time is fixed. The worker only needs to calculate the volume of the material discharge channel 4 to get the amount of material discharged each time.
