Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for grinding wheel manufacturing, and in particular to a grinding wheel mesh stacking rack that facilitates material handling. Background Technology

[0002] In the production process of resin-bonded grinding wheels, it is usually necessary to embed reinforcing mesh discs into the grinding wheel matrix to improve the structural strength and safety of the grinding wheel. These mesh discs need to be cut, classified and stored in an orderly manner before molding so that they can be automatically or manually picked up and placed into the mold for hot pressing.

[0003] Currently, common methods for storing abrasive wheel mesh include simple trays or upright supports. However, these traditional methods have significant drawbacks: due to the thin and smooth texture of the mesh material itself, as well as its hygroscopic and electrostatic tendencies, multiple stacked meshes are prone to adsorption effects and significant static friction, making it difficult to separate the meshes and causing issues with picking up pieces together. This necessitates repeated manipulation and lifting of the edges by operators or mechanical grippers when picking up the material, which is not only cumbersome and inefficient but also prone to tearing the edges of the mesh, affecting the subsequent molding quality.

[0004] Therefore, there is an urgent need to provide a grinding wheel mesh stacking rack that is easy to handle. Utility Model Content

[0005] In order to overcome the shortcomings of existing grinding wheel mesh stacking devices, such as difficulty in separating individual pieces during material handling and the simultaneous handling of pieces, resulting in low material handling efficiency, this utility model provides a grinding wheel mesh stacking rack that facilitates material handling.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a grinding wheel mesh stacking rack for easy material handling, comprising a base, two support rods symmetrically fixed to the top of the base, two sliding sleeves slidably fitted onto each support rod, a connecting rod fixedly connected to each sliding sleeve, a support plate fixedly disposed between two adjacent connecting rods, a first limiting plate fixedly disposed on the rear side of the support plate, a second limiting plate fixedly disposed on the front side of the support plate, an mounting plate fixedly disposed on the top of the first limiting plate, a sliding rod slidably passing through the mounting plate, and a spherical pressure block disposed at the bottom end of the sliding rod.

[0007] Furthermore, the support plate is arranged at an angle, with the front lower than the back.

[0008] Furthermore, each of the sliding sleeves is provided with a threaded sleeve on its outer side, and an adjusting screw is threadedly connected to the threaded sleeve, with the inner end of the adjusting screw facing the outer wall of the support rod.

[0009] Furthermore, a knob is provided at one end of the adjusting screw located outside the threaded sleeve.

[0010] Furthermore, four connecting plates are evenly spaced around the outer periphery of the base, and a fixing sleeve is fixedly installed on the connecting plate. A suction cup is installed at the bottom end of the fixing sleeve, and a vent pipe is slidably installed inside the fixing sleeve. A vent hole is opened on the side of the vent pipe, and an elastic element is sleeved on the upper end of the vent pipe. The two ends of the elastic element are fixedly connected to the connecting plate and the vent pipe, respectively.

[0011] Furthermore, a counterweight plate is provided at the center of the base.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting up a sliding rod and a spherical pressure block, the spherical pressure block squeezes the central area of ​​the mesh fabric disc, causing the center of the mesh fabric to be compressed and the edges to naturally curl upward, forming a separation gap that is easy for fingers or mechanical grippers to insert. This structure effectively overcomes the difficulties in picking up materials and the problem of picking up sheets along with the layers caused by interlayer adsorption and high friction in the traditional stacking method, and realizes rapid and accurate separation of single sheets, greatly improving the efficiency of manual or automated material picking.

[0013] 2. By setting an adjusting screw on the outside of the sliding sleeve, the height of the four sliding sleeves can be easily adjusted independently or in concert. After loosening the adjusting screw, the sliding sleeve can slide freely along the support rod. After locking, it is firmly fixed by the radial clamping force of the adjusting screw on the support rod. This structure allows the height of the support plate to be flexibly adjusted according to actual needs, greatly enhancing the versatility and applicability of the device.

[0014] 3. The suction cup fixing mechanism around the base, along with the suction cups, air pipes, and air holes, enables rapid clamping and release of the vacuum adsorption. When needed, the device can be firmly adsorbed onto a flat surface or workbench, effectively preventing the device from sliding or tipping over due to external forces or shift in the center of gravity during material handling, thus ensuring operational safety and orderly stacking of materials.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0023] Example 1: Please refer to Figures 1-3 A grinding wheel mesh stacking rack for easy material handling includes a base 1. Two support rods 2 are symmetrically fixed to the top of the base 1. Two sliding sleeves 3 are slidably fitted onto each support rod 2. A connecting rod 4 is fixedly connected to each sliding sleeve 3. A support plate 5 is fixedly arranged between two adjacent connecting rods 4. The support plate 5 is inclined, with the front lower than the back, facilitating the natural forward sliding of the stacked mesh discs under gravity, bringing them closer to the operator for easy observation and material handling. A first... The first limiting plate 6 and the second limiting plate 7 are fixedly installed on the front side of the support plate 5. The first limiting plate 6 and the second limiting plate 7 are used to restrict the grinding wheel mesh discs from sliding forward and backward during the stacking process. The first limiting plate 6 is fixedly installed on the top of the first limiting plate 6. A sliding rod 8 is slidably installed through the mounting plate 701. A spherical pressure block 9 is installed at the bottom end of the sliding rod 8. A counterweight plate 19 is installed at the center of the base 1 to improve the overall stability of the stacking rack and prevent the device from tipping over or shaking during use.

[0024] When using this device, the operator first pulls the sliding rod 8 upwards, causing the spherical pressure block 9 to detach from the stacking area, providing space for material loading. Then, multiple mesh fabric discs are sequentially stacked on the inclined support plate 5. Their outer edges are constrained by the first limiting plate 6 and the second limiting plate 7, ensuring that the stacking is neat and does not shift. After stacking is completed, the sliding rod 8 is released. Under its own weight, the sliding rod 8 moves downwards, and the spherical pressure block 9 descends and presses the central area of ​​the stacked mesh fabric discs. Because the mesh fabric material has a certain degree of flexibility, the center is compressed and undergoes local concave deformation, causing the edge of the uppermost mesh fabric disc to naturally curl upwards, forming a distinct arc-shaped curved edge. This curved edge provides the operator with a clear picking point, making it easy to insert fingers or mechanical grippers into the gap between the uppermost mesh fabric disc and the next layer, achieving separation and rapid material picking one by one, avoiding the problems of multiple discs being connected or difficult to pick up.

[0025] Example 2: Based on Example 1, please refer to... Figure 3 and Figure 4 Each of the sliding sleeves 3 has a threaded sleeve 10 on its outer side. An adjusting screw 11 is threaded onto the threaded sleeve 10. The inner end of the adjusting screw 11 faces the outer wall of the support rod 2. A knob 12 for easy manual operation is provided at the end of the adjusting screw 11 located outside the threaded sleeve 10.

[0026] When the height of the support plate 5 needs to be adjusted, first manually rotate the knob 12 to drive the adjusting screw 11 to rotate inside the threaded sleeve 10. By rotating the adjusting screw 11, its inner end is disengaged from the outer wall of the support rod 2, thereby releasing the radial clamping force on the sliding sleeve 3. At this time, the sliding sleeve 3 can slide freely on the support rod 2. Then, manually move the sliding sleeve 3 up and down along the support rod 2 to adjust it to the required height position. When the sliding sleeve 3 moves to the specified height, rotate the knob 12 in the opposite direction to drive the adjusting screw 11 to rotate in the opposite direction, causing its inner end to move radially inward until it is tightly pressed against the outer wall of the support rod 2. By adjusting the radial pressure applied to the support rod 2 by the adjusting screw 11, sufficient friction is generated to firmly fix the sliding sleeve 3 in the current position of the support rod 2, thereby locking the height.

[0027] Please see Figure 5 and Figure 6 The base 1 has four connecting plates 13 evenly spaced around its outer periphery. A fixing sleeve 14 is fixedly mounted on the connecting plate 13. A suction cup 15 is provided at the bottom end of the fixing sleeve 14. A vent pipe 16 is slidably mounted inside the fixing sleeve 14. A vent hole 18 is provided on the side of the vent pipe 16. An elastic element 17 is sleeved on the upper end of the vent pipe 16. The upper and lower ends of the elastic element 17 are fixedly connected to the connecting plate 13 and the vent pipe 16, respectively, to provide an upward restoring force for the vent pipe 16.

[0028] In the initial state, under the elastic force of the elastic element 17, the vent pipe 16 is located inside the fixed sleeve 14. In this position, the vent hole 18 on the side wall of the vent pipe 16 is not connected to the inner cavity of the suction cup 15, and the inner cavity of the suction cup 15 is sealed. When it is necessary to stably fix this device on the workbench or the ground, manually press down on the vent pipe 16, and the elastic element 17 will be compressed accordingly. As the vent pipe 16 moves downward, the vent hole 18 is exposed. At this time, the inner cavity of the suction cup 15 is connected to the outside atmosphere through the vent hole 18. While keeping the vent pipe 16 pressed down, the suction cup 15 is then... The surface is tightly pressed onto the flat, smooth support surface. Then, the pressure on the vent tube 16 is released. Under the restoring force of the elastic element 17, the vent tube 16 returns to its original position. When the vent tube 16 moves to its initial position, the vent hole 18 on its side wall moves out of the communication area and is resealed by the wall of the fixing sleeve 14, thereby cutting off the passage between the inner cavity of the suction cup 15 and the external atmosphere. This creates a sealed negative pressure space in the inner cavity of the suction cup 15. The external atmospheric pressure is much greater than the pressure in the inner cavity of the suction cup 15, thereby generating a strong suction force that firmly adheres the suction cup 15 and the entire stacking rack to the support surface.
