Description

Technical Field

[0001] This utility model relates to the field of grinding wheel manufacturing equipment technology, and in particular to a netting device for a grinding wheel forming unit. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are made by bonding ordinary abrasives into a certain shape and giving them a certain strength. They are generally composed of abrasives, bonding agents, and pores. Grinding wheel forming machines are specially designed to produce grinding wheels.

[0003] In the production of grinding wheel forming units, after the grinding wheel lower die spreads the forming material evenly, the grinding wheel upper die needs to cover and adhere to the grinding wheel lower die and the forming material; then the combination of the grinding wheel lower die and the grinding wheel upper die is sent into the hydraulic press to form the grinding wheel.

[0004] To enhance the strength of the grinding wheel after pressing, multiple layers of mesh cloth are placed inside the grinding wheel and pressed together with other materials, resulting in a stronger grinding wheel. For example, the utility model patent with authorization publication number CN207448251U discloses an automatic mesh-adhesive device, which moves to the grinding wheel processing station through a horizontal drive mechanism and then uses a mesh-adhesive and mesh-placement mechanism to place the mesh on the station to complete the mesh placement of the grinding wheel.

[0005] The aforementioned public document discloses the process of attaching and placing the mesh on the grinding wheel, but there are still some defects. The multi-layer mesh placed on the work station is placed completely randomly, which causes the warp and weft threads of the mesh to be randomly arranged, making the grinding wheel easy to deform during the pressing and molding process. Summary of the Invention

[0006] To address the problem of existing grinding wheels being easily deformed during the pressing and forming process due to the completely random placement of multiple layers of mesh, this invention proposes a mesh-adhesive and placement device for a grinding wheel forming unit. The mesh-adhesive and placement mechanism removes the mesh from the mesh lifting mechanism and moves it to the upper end of the grinding wheel template under the drive of the horizontal drive mechanism. Then, the rotating component in the mesh-adhesive and placement mechanism rotates to align the warp and weft threads of the multiple meshes before placing them into the grinding wheel template, further improving the strength of the grinding wheel.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A wire mesh placement device for a grinding wheel forming unit is provided for placing wire mesh into a grinding wheel template. The wire mesh placement device includes a frame, a wire mesh lifting mechanism, a wire mesh placement mechanism, and a horizontal drive mechanism. The wire mesh placement mechanism is located above the wire mesh lifting mechanism. The wire mesh lifting mechanism lifts the wire mesh to the lower end of the wire mesh placement mechanism, and the wire mesh placement mechanism adheres to the wire mesh. The horizontal drive mechanism drives the wire mesh placement mechanism to slide horizontally on the frame to the top of the grinding wheel template, and the wire mesh placement mechanism places the wire mesh into the grinding wheel template. The wire mesh includes multiple warp threads and multiple weft threads, which are arranged in parallel and perpendicular to each other. The wire mesh placement mechanism includes a rotating component, which drives the wire mesh to rotate so that the warp threads or weft threads of the multiple wire meshes are aligned vertically.

[0009] Furthermore, the mesh is circular.

[0010] Furthermore, the netting device also includes a detection component and a control component. The detection component includes a positioning groove on the upper end of the grinding wheel template. The detection component is used to detect the angle between the warp thread in the middle of the net and the positioning groove or the angle between the weft thread in the middle of the net and the positioning groove. The control component is used to control the rotation angle of the output end of the rotation component.

[0011] Furthermore, the adjacent positioning slots are arranged perpendicularly. Four positioning slots are provided on the grinding wheel template.

[0012] Furthermore, the detection component also includes a camera, and the control component includes an engineering controller and a PLC controller. The camera is located above the positioning slot, and its output is connected to the input of the engineering controller. The output of the engineering controller is connected to the input of the PLC controller, and the output of the PLC controller is connected to the input of the rotation component. After analyzing the images captured by the camera, the engineering controller determines the required rotation angle of the mesh and then transmits the signal to the PLC controller.

[0013] Furthermore, the mesh lifting mechanism includes a support frame, a support plate, a positioning frame, a first telescopic mechanism, a sliding plate, a sliding rod, and a tray. The support plate is fixed to the upper end of the support frame, the positioning frame is fixed to the lower side of the support plate, the first telescopic mechanism is fixed to the positioning frame, the sliding plate is slidably disposed on the positioning frame, the output end of the first telescopic mechanism passes upward through the positioning frame and is fixedly connected to the sliding plate, and the sliding rod is fixed to the sliding plate, with its upper end passing through the support plate and fixedly connected to the tray.

[0014] Furthermore, the mesh lifting mechanism also includes a guide rod fixed to the support plate, and the tray is slidably sleeved on the guide rod.

[0015] Furthermore, the net-attaching mechanism also includes a sliding seat, a second telescopic mechanism, a mounting frame, a push plate, a tape roll, a take-up tape wheel, a limiting member, and a first power mechanism. The sliding seat is slidably mounted on the frame, and the rotating assembly is located on the lower side of the sliding seat. The second telescopic mechanism is fixed to the output end of the rotating assembly. The mounting frame is fixedly connected to the second telescopic mechanism, and the output end of the second telescopic mechanism extends downward from the mounting frame and is fixedly connected to the push plate. The tape roll and the take-up tape wheel are both rotatably mounted on the outside of the mounting frame. The first power mechanism drives the take-up tape wheel to rotate. The limiting member is fixed on the mounting frame and located between the tape roll and the take-up tape wheel. One end of the tape roll extends downward through the lower side of the limiting member and connects to the take-up tape wheel. The lower side of the limiting member is lower than the lower side of the push plate. The adhesive surface of the tape roll is located on the lower side of the limiting member and lower than the push plate. When the push plate is in its original position, the adhesive surface of the tape roll is always the lowest surface in the net-attaching mechanism, thus adhering the net.

[0016] Furthermore, the first power mechanism includes a third telescopic mechanism, a rack, and a gear. The belt take-up pulley is rotatably mounted on the mounting frame via a rotating shaft.

[0018] Through the above technical solution, the beneficial effects of this utility model are as follows: the netting mechanism in this utility model takes out the netting from the netting lifting mechanism and moves it to the upper end of the grinding wheel template under the drive of the horizontal driving mechanism. Then, the rotating component in the netting mechanism rotates so that the warp and weft of multiple nettings are aligned and then placed into the grinding wheel template, further improving the strength of the grinding wheel.

[0039] The mesh lifting mechanism 4 also includes a guide rod 48 fixed on the support plate 42, and the tray 47 is slidably sleeved on the guide rod 48.

[0040] refer to Figures 5-8 The adhesive netting mechanism 5 also includes a sliding seat 52, a second telescopic mechanism 53, a mounting frame 54, a push plate 55, a tape roll 56, a tape take-up wheel 57, a limiting member 58, and a first power mechanism.

[0041] The sliding seat 52 is slidably mounted on the frame 3. A slide rail 11 is fixed on the frame 3. A slider that cooperates with the slide rail 11 is fixed on the sliding seat 52 to realize the sliding of the sliding seat 52 on the frame 3.

[0042] The rotating assembly 51 is disposed on the lower side of the sliding seat 52, and the second telescopic mechanism 53 is fixed on the output end of the rotating assembly 51. The rotating assembly 51 includes a second motor 511, two second pulleys 512, a second transmission belt 513, and a bearing 514. The second motor 511 is fixed on the lower side of the sliding seat 52, one of the second pulleys 512 is fixed on the output end of the second motor 511, the bearing 514 is rotatably disposed inside the sliding seat 52 with the transmission shaft, the lower end of the transmission shaft extends out of the sliding seat 52, the other second pulley 512 is fixedly sleeved on the transmission shaft, and the second transmission belt 513 is wound around the outside of the two second pulleys 512. When the second motor 511 is started, it drives the transmission shaft to rotate. The upper end of the second telescopic mechanism 53 is fixedly connected to the transmission shaft. The second telescopic mechanism 53 can be a cylinder or a hydraulic cylinder.

[0043] The mounting bracket 54 is fixedly connected to the second telescopic mechanism 53, and the output end of the second telescopic mechanism 53 extends downward out of the mounting bracket 54 and is fixedly connected to the push plate 55.

[0044] Both the tape roll 56 and the take-up pulley 57 are rotatably mounted on the outside of the mounting frame 54. The first power mechanism drives the take-up pulley 57 to rotate. The limiting member 58 is fixed on the mounting frame 54 and located between the tape roll 56 and the take-up pulley 57. One end of the tape roll 56 extends downward through the lower side of the limiting member 58 and connects to the take-up pulley 57. The lower side of the limiting member 58 is lower than the lower side of the push plate 55.

[0045] In this embodiment, the limiting member 58 passes downward through the push plate 55 and has a gap between it and the push plate 55, allowing the tape roll 56 to pass through the gap between the limiting member 58 and the push plate 55 and be connected and fixed to the tape take-up pulley 57. The tape rolls 56 are symmetrically arranged on both sides of the mounting frame 54, with two rolls on each side, which makes the adhesion of the mesh sheet 1 more stable.

[0046] The mesh sheet 1 is threaded onto the guide rod 48. When the mesh sheet 1 needs to be removed, the first telescopic mechanism 44 extends, so that the mesh sheet 1 slides upward along the guide rod 48 and lifts the mesh sheet 1 on the tray 47. Thus, the uppermost mesh sheet 1 adheres to the tape roll 56 on the lower side of the limiting member 58. At this time, the first telescopic mechanism 44 retracts, and the remaining mesh sheet 1 descends, completing one removal of the mesh sheet 1.

[0047] Furthermore, the first power mechanism includes a third telescopic mechanism 591, a rack 592, and a gear 593. The take-up pulley 57 is rotatably mounted on the mounting frame 54 via a rotating shaft 594. The third telescopic mechanism 591 is fixed to the mounting frame 54, and its output end is fixedly connected to the rack 592. The gear 593 is fixedly sleeved on the rotating shaft 594 and meshes with the rack 592. After multiple adhesions of the mesh 1, the adhesion of this adhesion point on the tape roll 56 decreases. Therefore, the first power mechanism drives the take-up pulley 57 to rotate, thereby changing the adhesion point of the tape roll 56 and maintaining adhesion stability.

[0048] refer to Figure 8 The horizontal drive mechanism 6 includes a first motor 61, two first pulleys 62, and a first transmission belt 63. The first motor 61 is fixed to the frame 3, and its output end passes through the frame 3 and is fixedly connected to one of the first pulleys 62. The other first pulley 62 is rotatably mounted on the frame 3. The first transmission belt 63 is sleeved on the outside of the two first pulleys 62. The sliding seat 52 is fixedly connected to the first transmission belt 63. In this device, the first transmission belt 63 only needs to move horizontally left and right, so the fixed connection between the sliding seat 52 and the first transmission belt 63 will not cause positional interference. Under the power of the first motor 61, the sliding seat 52 will move horizontally back and forth on the frame 3.

[0049] In this embodiment, mounting screws 10 are fixed on the frame 3 for connecting with external components, thereby ensuring the stability of the frame 3.

[0050] When using this device, the mesh placement mechanism 5 is located above the mesh lifting mechanism 4. At this time, the first telescopic mechanism 44 extends, and the mesh 1 slides upward along the guide rod 48 to lift the mesh 1 on the tray 47. Thus, the uppermost mesh 1 adheres to the tape roll 56 on the lower side of the limiting member 58. At this time, the first telescopic mechanism 44 retracts, and the remaining mesh 1 descends, completing one mesh 1 picking. The first motor 61 is started, and the first transmission belt 63 drives the sliding seat 52 to move horizontally on the frame 3 to above the grinding wheel template 2. The camera located above the grinding wheel template 2 takes a set of photos and uploads them to the project manager. After analyzing the photos taken by the camera, the project controller obtains the angle that the mesh 1 needs to rotate at this time, and then transmits the signal to the PLC controller. The PLC controller controls the rotation angle of the mesh 1 to achieve the vertical correspondence of the warp 7 or weft 8 of multiple mesh 1. The third telescopic mechanism 591 extends downward, and the push plate 55 at its lower end puts the mesh 1 into the grinding wheel template 2. The subsequent mesh 1 placement work can continue according to the above steps.

[0051] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
