Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a blanking mechanism for a sponge roller grinder. Background Art

[0002] The sponge charging roller is an important component in the printer, used to apply electrostatic charge to the toner drum during the printing process. It usually includes a roller shaft and a foamed conductive sponge layer sleeved outside the roller shaft, and a sleeve sleeved outside the foamed conductive sponge layer.

[0003] When producing charging rollers, the roller shafts need to be machined. After machining is complete, the rollers need to be removed from the processing equipment, known as blanking. However, blanking currently presents a problem: after machining is complete, the machine must be shut down and the finished rollers manually placed into a collection basket. This requires a machine stop after each completed roller, resulting in long downtimes and ineffective processing efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a highly efficient and labor-saving sponge charging roller grinder to solve the problems mentioned in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A feeding mechanism for a sponge roller grinder comprises a frame, the top of the frame is connected to a first cylinder, the telescopic end of the first cylinder is connected to an L-shaped plate, the bottom surface of one side of the L-shaped plate is connected to a guide rail, the top of the first cylinder is connected to a limit block, the top surface of the limit block is provided with a slide groove, the guide rail is slidably connected in the slide groove, the other side of the L-shaped plate is connected to a second cylinder, the telescopic end of the second cylinder is connected to a U-shaped seat, a displacement adjustment mechanism is installed on the U-shaped seat, and a grabbing mechanism is connected through the displacement adjustment mechanism; an outwardly extending belt conveyor is installed on the upper part of the frame, and the belt conveyor is located below the first cylinder.

[0007] Preferably, the displacement adjustment mechanism includes a screw rod rotatably connected to the U-shaped seat, a guide rod connected to the U-shaped seat, a first motor installed at one end of the U-shaped seat, and a slide threadedly connected to the screw rod. The first motor is transmission-connected to the screw rod, the slide is slidingly connected to the guide rod, and the gripping mechanism is installed on the bottom surface of the slide.

[0008] In the above technical solution, the first motor is started to drive the screw to rotate, which can drive the slide to slide on the guide rod, thereby adjusting the position of the grasping mechanism so that the grasping mechanism can accurately grasp the shaft roller.

[0009] Preferably, the gripping mechanism includes a finger cylinder and a splint connected to the two fingers of the finger cylinder. The lower parts of the opposite surfaces of the two splints are provided with protrusions that are close to each other. The two ends of the protrusions are connected with round cakes. The distance between the two round cakes at the same end of the two splints is smaller than the distance between the two protrusions.

[0010] The above technical solution drives the two clamping plates to move relative to each other through the operation of the finger cylinder, thereby clamping the shaft roller between the two clamping plates. The shaft roller is located above the protrusion, and the two ends of the shaft roller are located on the round cake, which can effectively prevent the shaft roller from falling.

[0011] Preferably, the belt conveyor includes two side plates connected to the frame, two rotating shafts rotatably connected between the two side plates, a support plate connected to the top surfaces of the two side plates, a conveyor belt transmission-connected to the two rotating shafts, a second motor mounted on the frame, a transmission shaft connected to the second motor through a coupling, a driving wheel connected to the transmission shaft, and a driven wheel connected to one of the rotating shafts, and the driving wheel and the driven wheel are connected by a transmission belt.

[0012] The above technical solution starts the second motor to drive the conveyor belt to rotate, thereby conveying the shaft roller, and the support plate supports the conveyor belt to prevent the conveyor belt from collapsing.

[0013] Preferably, the top surface of the side plate close to one end of the frame is an inclined surface inclined toward the support plate, and the end of the side plate away from the frame is connected to a limiting rod protruding upward.

[0014] In the above technical solution, after the grabbing mechanism places the shaft roller on the side plate, it enters the conveyor belt along the inclined surface of the side plate, and transports the shaft roller forward through the conveyor belt. The limit rod can stop the shaft roller from moving forward and prevent the shaft roller from falling. After the required number of shaft rollers is reached, the shaft rollers are removed one by one.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] After the roller processing is complete, the first pneumatic cylinder is controlled to extend, pushing the L-shaped plate outward. This is then controlled to extend, driving the gripping mechanism downward. The displacement adjustment mechanism adjusts the gripping mechanism's position to align with the roller. The gripping mechanism then grabs the roller and places it on the belt conveyor, which then transports it forward. This entire unloading process eliminates the need for manual handling of the roller and machine downtime, improving processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The displacement adjustment mechanism includes a screw 8 rotatably connected to the U-shaped seat, a guide rod 9 connected to the U-shaped seat, a first motor 10 mounted at one end of the U-shaped seat, and a slide 11 threadedly connected to the screw. The first motor 10 is in driving connection with the screw 8, the slide 11 is slidably connected to the guide rod 9, and a gripping mechanism is mounted on the bottom surface of the slide 11. The gripping mechanism includes a finger cylinder 12 connected to the bottom surface of the slide 11, and a clamping plate 13 connected to the two fingers of the finger cylinder. The lower portions of the opposing surfaces of the two clamping plates 13 are provided with mutually approaching protrusions, and the two ends of the protrusions are connected to round discs 14. The spacing between the two round discs 14 at the same end of the two clamping plates 13 is smaller than the spacing between the two protrusions to prevent the shaft roller from falling. Start the first motor 10 and drive the screw 8 to rotate, which can drive the slide 11 to slide on the guide rod 9, thereby adjusting the position of the finger cylinder 12, and then control the finger cylinder to work, driving the two clamping plates to move relative to each other, thereby clamping the shaft roller between the two clamping plates, so that the shaft roller is located above the protrusion, and the two ends of the shaft roller are located on the round cake, effectively preventing the shaft roller from falling.

[0025] An outwardly extending belt conveyor is mounted on the upper portion of the frame 1 and is located below the first cylinder 2. The belt conveyor comprises two side plates 15 connected to the frame, two rotating shafts 16 rotatably connected between the side plates, a support plate 17 connected to the top surfaces of the side plates, a conveyor belt 18 transmission-connected to the two rotating shafts, a second motor 19 mounted on the frame, a transmission shaft connected to the second motor via a coupling, a driving pulley 20 connected to the transmission shaft, and a driven pulley 21 connected to one of the rotating shafts, wherein the driving pulley 20 and the driven pulley 21 are connected by a transmission belt 22.

The support plate 17 supports the conveyor belt 18 to prevent it from collapsing.

[0026] The working principle of this embodiment is:

[0027] After the processing of the shaft roller 24 is completed, the first cylinder 4 is controlled to extend to push the L-shaped plate 3 to move outward. At the same time, the position of the finger cylinder 12 is adjusted through the displacement adjustment mechanism to align it with the shaft roller. Then the second cylinder 6 is controlled to extend to drive the U-shaped seat 7 to move downward, and the shaft roller is grabbed by the finger cylinder 12. After grabbing, the second cylinder 6 is controlled to retract, the first cylinder 4 is retracted, and the shaft roller is placed on the belt conveyor and transported forward by the belt conveyor.
