Description

Technical Field

[0001] This invention relates to the field of grinding wheel equipment manufacturing technology, and more specifically, to a mechanism for separating wheel mesh and waste material. Background Technology

[0002] Most abrasive grinding wheel screens are circular. During the final production of the screens, the raw material needs to be punched into several circular screens using a punching tool. After cutting, the circular screens are embedded in the raw material. Therefore, before collecting the screens, they need to be separated from the raw material to facilitate separate collection of the screens and waste materials. However, since there is still some adhesion between the screens and the waste material immediately after cutting, adhesion often occurs when separating them. This adhesion particularly affects the collection of waste materials because the waste materials are transported to the waste collection box via the conveyor surface. Adhesion between the screens and the waste materials easily hinders their transfer to the collection box. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a separation mechanism for wheel mesh and waste.

[0004] To achieve the above objectives, the innovative aspects of this invention are as follows. Its structure includes a frame, on which a fiberglass mesh conveying surface is provided. At the end of the conveying surface, a cutting station for abrasive mesh is provided. The cutting station has a horizontally aligned transfer station for guiding the cut fiberglass mesh from the conveying surface. A waste collection box is located on one side of the transfer station. A vertically adjustable tray is located directly below the transfer station. Several vertically upward-facing push rods are distributed on the tray, with vacuum suction cups at the top of each push rod. All push rods are rotatably mounted on the tray. The distribution of the push rods on the tray corresponds one-to-one with the distribution of the abrasive mesh on the transfer station, allowing the push rods to lift the abrasive mesh when they move upwards. When the push rod lifts the grinding wheel mesh, the vacuum suction cup holds the grinding wheel mesh while the push rod rotates adaptively in sync.

[0005] Furthermore, a support frame is provided on one side of the aforementioned cutting station, and a fixed frame parallel to the horizontal plane is fixed on the support frame. Two parallel and freely rotatable receiving roller tracks are provided at both ends of the fixed frame. One of the receiving roller tracks is set close to the end of the transmission surface, and the two receiving roller tracks form a transfer station. Between the two receiving rollers, there are several parallel tension ropes. The distance between any two adjacent tension ropes is the same, forming a clearance zone. The top rod is set directly below the clearance zone.

[0006] Furthermore, a fixing plate is fixed below the aforementioned fixed frame, and several guide columns are provided between the fixing plate and the fixed frame. The support plate is slidably mounted on the guide columns. The fixing plate is provided with a driving component that drives the support plate to move up and down. When the top rod lifts the grinding wheel mesh, the driving component synchronously drives the top rod to rotate adaptively.

[0007] Furthermore, the aforementioned driving component includes a rotary motor and a lead screw nut located at the center of the pallet. The rotary motor is fixed on the fixed plate, and the output end of the rotary motor is provided with a connecting rod. An adjusting lead screw extends vertically upward from the connecting rod and is threaded onto the lead screw nut.

[0008] Furthermore, the bottom of the aforementioned push rod is provided with an extension rod extending below the support plate, the extension rod is provided with a driven wheel, the bottom of the support plate is provided with a rotatable driving wheel, a belt is tensioned between several driven wheels and driving wheels, a rotating rod extends downward from the center of the driving wheel, the bottom of the rotating rod is provided with a driven clutch gear, the connecting rod is provided with a driving clutch gear, when the push rod lifts the grinding wheel mesh, the height of the driving clutch gear and the driven clutch gear are aligned and they mesh with each other.

[0009] Furthermore, the top of the aforementioned push rod is provided with a U-shaped rod, and both ends of the U-shaped rod are provided with vacuum suction cups. The push rod extends upward with a positioning rod, which is located between the two vacuum suction cups. When the push rod lifts the grinding wheel mesh, the positioning rod passes through the central hole of the grinding wheel mesh and the two vacuum suction cups abut against the circular surface of the grinding wheel mesh.

[0010] Furthermore, the aforementioned positioning rod is provided with a circular contact surface, the height of which is the same as the height of the vacuum suction cup. The vacuum suction cup is provided with a controller to control opening or closing, and a contact switch is provided on the contact surface. The contact switch and the controller are electrically connected.

[0011] The technical effects and advantages of this invention are as follows: When the top rod lifts the grinding wheel mesh, the vacuum suction cup on the top rod adsorbs and fixes the grinding wheel mesh, preventing it from shaking arbitrarily. At the same time, the top rod rotates adaptively, which allows the grinding wheel mesh embedded in the fiberglass mesh to be quickly separated from the waste material of the fiberglass mesh, avoiding adhesion between the grinding wheel mesh and the fiberglass mesh. This ensures that when the grinding wheel mesh and the fiberglass mesh are separated, the waste material of the fiberglass mesh can be stably conveyed to the waste collection box and collected.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figs. 1 to 4 In one specific embodiment of the present invention, the structure includes a frame 1, on which a glass fiber mesh cloth transmission surface 11 is provided. At the transmission end of the transmission surface 11, a cutting station 12 for abrasive mesh is provided. The cutting station 12 is provided with a horizontally aligned transfer station 13. The transfer station 13 is used to guide and dock the glass fiber mesh cloth cut on the transmission surface 11. A waste collection box 14 is provided on one side of the transfer station 13. A vertically adjustable pallet 15 is provided directly below the transfer station 13. Several vertically upward-facing push rods 16 are distributed on the pallet 15. A vacuum suction cup 17 is provided on the top of the push rods 16. The push rods 16 are rotatably mounted on the pallet 15. The distribution positions of the push rods 16 on the pallet 15 correspond one-to-one with the distribution positions of the abrasive mesh on the transfer station 13, so that the push rods 16 can lift the abrasive mesh when they move upward. When the push rod 16 lifts the grinding wheel mesh, the vacuum suction cup 17 holds the grinding wheel mesh and the push rod 16 rotates adaptively in sync.

[0017] In this invention, the process of separating the cut abrasive mesh sheets and waste is as follows: As the fiberglass mesh is conveyed by the conveyor surface 11, it passes through the cutting station 12. Under the action of external cutting tools and according to the requirements of the cutting scheme, the fiberglass mesh is cut into several circular abrasive mesh sheets. At this time, the cut abrasive mesh sheets are embedded in the fiberglass mesh. As the conveyor surface 11 continues to convey the material, the cut fiberglass mesh enters the transfer station 13, at which point the conveyor surface 11 stops conveying the material. The abrasive mesh is then separated according to the requirements of the cutting scheme. The cutting scheme involves pre-arranging the positions of the push rods 16 on the pallet 15. After the cut fiberglass mesh enters the transfer station 13, the distribution positions of the push rods 16 correspond one-to-one with the distribution positions of the grinding wheel mesh on the transfer station 13. Then, the pallet 15 is moved upward, and the push rods 16 lift the grinding wheel mesh from the transfer station 13, separating the waste from the waste of the grinding wheel mesh and the fiberglass mesh. The waste of the fiberglass mesh continues to be conveyed and falls into the waste collection box 14 for collection, thus realizing the automatic separation of the grinding wheel mesh and the waste.

[0018] In this invention, when the top rod 16 lifts the grinding wheel mesh, the vacuum suction cup 17 on the top rod 16 adsorbs and fixes the grinding wheel mesh, preventing the grinding wheel mesh from shaking arbitrarily. At the same time, the top rod 16 rotates adaptively. This rotation allows the grinding wheel mesh embedded in the fiberglass mesh to be quickly separated from the waste material of the fiberglass mesh, avoiding the phenomenon of adhesion between the grinding wheel mesh and the fiberglass mesh. This ensures that when the grinding wheel mesh and the fiberglass mesh are separated, the waste material of the fiberglass mesh can be stably conveyed to the waste collection box 14 and collected.

[0019] In this invention, as a preferred embodiment, a support frame 2 is provided on one side of the cutting station 12, and a fixed frame 21 parallel to the horizontal plane is fixed on the support frame 2. Two parallel and freely rotatable receiving roller tracks 22 are provided at both ends of the fixed frame 21. One of the receiving roller tracks 22 is set close to the transmission end of the transmission surface 11, and the two receiving roller tracks 22 form a transfer station 13. Between the two receiving roller conveyors 22, there are several parallel tension ropes 23. The distance between any two adjacent tension ropes 23 is the same and forms a clearance zone 24. The top rod 16 is set directly below the clearance zone 24.

[0020] In this invention, when the cut fiberglass mesh enters the transfer station 13, the rotation of the two receiving rollers 22 enables the cut fiberglass mesh to quickly enter the transfer station 13. At the same time, the tension rope 23 can support the cut abrasive mesh, and the setting of the avoidance area 24 can also facilitate the subsequent entry of the lower push rod 16 and lift the cut abrasive mesh upward.

[0021] In this invention, as a preferred embodiment, a fixing plate 3 is fixed below the fixing frame 21, and a plurality of guide posts 31 are provided between the fixing plate 3 and the fixing frame 21. The support plate 15 is slidably mounted on the guide posts 31. The fixing plate 3 is provided with a driving member 4 for driving the support plate 15 to move up and down. When the top rod 16 lifts the grinding wheel mesh, the driving member 4 synchronously drives the top rod 16 to rotate adaptively.

[0022] In this invention, the guide post 31 can guide the up and down movement of the pallet 15, ensuring the stability of the up and down movement of the pallet 15. Secondly, in addition to driving the pallet 15 to move up and down, the drive member 4 can also drive the push rod 16 to rotate adaptively without providing additional power for the rotation of the push rod 16, thereby saving energy.

[0023] In this invention, as a preferred embodiment, the drive component 4 includes a rotary motor 41 and a lead screw nut 42 located at the center of the support plate 15. The rotary motor 41 is fixed on the fixing plate 3. The output end of the rotary motor 41 is provided with a connecting rod 5. The connecting rod 5 extends vertically upward with an adjusting lead screw 51. The adjusting lead screw 51 passes through and is threadedly connected to the lead screw nut 42.

[0024] In this invention, the working principle of the drive component 4 is as follows: the rotation of the push rod 16 is powered by the rotary motor 41, and under the action of the thread of the adjusting screw 51 and the screw nut, the support plate 15 is driven to move up and down.

[0025] In this invention, as a preferred embodiment, the bottom of the aforementioned push rod 16 is provided with an extension rod 52 extending below the support plate 15, the extension rod 52 is provided with a driven wheel 53, the bottom of the support plate 15 is provided with a rotatable driving wheel 54, a belt 55 is tensioned between several driven wheels 53 and driving wheels 54, a rotating rod 56 extends downward from the center of the driving wheel 54, the bottom of the rotating rod 56 is provided with a driven clutch gear 57, the connecting rod 5 is provided with a driving clutch gear 58, when the push rod 16 lifts the grinding wheel mesh, the height of the driving clutch gear 58 and the driven clutch gear 57 are aligned and they mesh with each other.

[0026] In this invention, under the action of belt 55, the rotation of drive wheel 54 drives all driven wheels 53 to rotate, thereby driving all push rods 16 to rotate. Meanwhile, rotary motor 41 drives connecting rod 5 to rotate. Drive clutch gear 58 is always rotating. When push rod 16 lifts the grinding wheel mesh, the height of drive clutch gear 58 and driven clutch gear 57 are aligned and they mesh. At this time, drive clutch gear 58 can drive driven clutch gear 57 to rotate, thereby driving rotating rod 56 to rotate, thus causing drive wheel 54 to rotate, achieving the rotation of all push rods 16. When the height of drive clutch gear 58 and driven clutch gear 57 are not aligned, they are in a disengaged state, and push rod 16 does not need to rotate. This is because push rod 16 has not yet lifted the grinding wheel mesh, or push rod 16 has already lifted the grinding wheel mesh and left the transfer station 13. In this invention, as a preferred embodiment, the top of the top rod 16 is provided with a U-shaped rod 6, and both ends of the U-shaped rod 6 are provided with vacuum suction cups 17. The top rod 16 extends upward with a positioning rod 61, which is located between the two vacuum suction cups 17. When the top rod 16 lifts the grinding wheel mesh, the positioning rod 61 passes through the central hole of the grinding wheel mesh and the two vacuum suction cups 17 abut against the circular surface of the grinding wheel mesh.

[0027] In this invention, the center of the grinding wheel mesh has a central hole, and the positioning rod 61 is set through this central hole to position the upward movement of the top rod 16. Secondly, due to the existence of the central hole, the vacuum suction cup 17 needs to avoid this central hole to ensure that the vacuum suction cup 17 can adsorb the grinding wheel mesh. The two ends of the U-shaped rod 6 are located on both sides of the positioning rod 61, so that the vacuum suction cup 17 can adsorb the grinding wheel mesh from the circular surfaces on both sides of the central hole.

[0028] In this invention, as a preferred embodiment, the positioning rod 61 is provided with a circular contact surface 7, the height of the contact surface 7 is the same as the height of the vacuum suction cup 17, the vacuum suction cup 17 is provided with a controller for controlling opening or closing, the contact surface 7 is provided with a contact switch, and the contact switch and the controller are electrically connected.

[0029] In this invention, the contact surface 7 and the vacuum suction cup 17 are at the same height. When the contact surface 7 contacts the grinding wheel mesh, it means that the vacuum suction cup 17 is also in contact with the grinding wheel mesh. At this time, the contact switch transmits a signal to the controller, and the controller opens the vacuum suction cup 17, which then adsorbs the grinding wheel mesh.

[0030] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.

Secondly: The accompanying drawings of the embodiments disclosed in this invention only involve the structures involved in the embodiments disclosed in this invention.
