DETAILED DESCRIPTION
[0026] like Figure 1-5 As shown, the utility model provides a screening device for recycling waste porcelain, comprising: a frame 10, a screening member 20, a rolling mechanism 30 and a vibration generator 40 rigidly connected to the screening member 20; wherein the frame 10 comprises a fixed bracket 11, a movable frame 12 with one end hinged to the fixed bracket 11, a lifting mechanism arranged on the fixed bracket 11 and a plurality of elastic members 14 arranged on the movable frame 12, the top end of the lifting mechanism is connected to the movable frame 12 for driving the movable frame 12 to rotate; the screening member 20 is connected to the upper ends of the plurality of elastic members 14, the screening member 20 comprises a box 21 and a screen 22 arranged at the bottom of the box 21; the rolling mechanism 30 is arranged on the movable frame 12, the rolling mechanism 30 comprises two linear reciprocating driving members 31 and a roller 32, the two ends of the roller 32 are respectively rotatably connected to the execution ends of the two linear reciprocating driving members 31, and the surface of the roller 32 is in contact with the bottom surface of the screen 22.
[0027] Compared with the prior art, the screening device for recycling waste porcelain provided in the embodiment of the utility model, under the action of the lifting mechanism, lifts up the movable frame 12 and the screening member 20 arranged on the movable frame 12 to be in an inclined state, and then drives the roller 32 to roll on the bottom of the screen 22 through the synchronous operation of two linear reciprocating drive members 31 (the roller 32 rolls through the friction between the roller 32 and the screen 22), which can loosen part of the broken porcelain blocked in the mesh, and start the vibration generator 40 to shake off the loosened broken porcelain. If it is not completely cleaned up at one time, it can be performed several times, thereby solving the problem of the screen 22 being blocked by broken porcelain and affecting the screening efficiency. At the same time, it can reduce manual labor, reduce the workers' exposure to a large amount of dust, and improve the working environment.
[0028] It should be noted that the box body 21 has a box cover, and an openable and closable movable door is provided at the end of the box body 21 near the hinge, which is used to remove the broken porcelain left on the screen 22. Figure 1 In order to show the screen 22, the box cover and the movable door are not shown.
[0029] In this embodiment, please refer to Figure 2 The rolling mechanism 30 also includes a rack 33 disposed on the movable frame 12 . The rack 33 is matched with a gear 34 . The gear 34 is coaxially fixedly connected to the connecting shaft of the roller 32 .
[0030] Specifically, the rack 33 is fixed to the side frame of the movable frame 12 by welding or screws. When the linear reciprocating drive member 31 drives the roller 32, the gear 34 engages with the rack 33 and rolls forward, thereby driving the roller 32 to roll and roll the screen 22. In this way, compared with the friction between the roller 32 and the screen 22, which causes the roller 32 to roll passively, the gear 34 engages with the rack 33 to cause the roller 32 to roll actively, which can reduce external interference and make the rolling of the roller 32 more stable and efficient.
[0031] In this embodiment, please refer to Figure 2 The linear reciprocating driving member 31 includes a motor, a ball screw drivingly connected to the motor, and a bearing seat 312 rigidly connected to a nut seat 311 of the ball screw, and the bearing seat 312 is connected to the connecting shaft of the roller 32 .
[0032] Specifically, the motor and the ball screw are arranged on a fixed plate, which is a component of the linear reciprocating drive member 31. The fixed plate is welded or screwed to the side of the movable frame 12 through at least two square tubes, and pays attention to avoiding the elastic member 14. The motor starts to drive the ball screw, so that the nut seat 311 moves linearly while driving the bearing seat 312 to move synchronously. Through the synchronous operation of the two linear reciprocating drive members 31, the roller 32 is driven to move linearly.
[0033] It should be noted that when the roller 32 moves, if the bottom surface of the screen 22 is uneven, the roller 32 can pass smoothly through the elastic member 14 by means of its expansion and contraction.
[0034] In this embodiment, the motor is a servo motor, a reduction motor or a stepping motor.
[0035] In this embodiment, the lifting mechanism includes a lifter 131 connected to the fixed bracket 11, a support frame hinged to the end of the lifter 131, and a plurality of limit pins 135 rigidly connected to the fixed bracket 11. The support frame is provided with a plurality of arc-shaped guide grooves 134, the limit pins 135 are slidably matched with the arc-shaped guide grooves 134, and the top of the support frame is rigidly connected to the movable frame 12.
[0036] Specifically, the lifter 131 is an oil cylinder, an electric cylinder or a pneumatic cylinder, and both ends of the lifter 131 are hinged to provide freedom of movement. One end of the limit pin 135 is vertically fixed on the fixed bracket 11, and the other end is passed through the arc guide groove 134, which can improve the stability of the support frame. The lifter 131 is started to lift the support frame to move in an arc trajectory, raising or lowering one end of the movable frame 12, thereby adjusting the posture of the screening element 20, specifically adjusting the inclination angle within the range of 0-90°.
[0037] In one embodiment, the support frame includes at least two support plates 132 and connecting rods 133 whose two ends are respectively connected to the two support plates 132 in a fixed axis, the connecting rods 133 are hinged to the ends of the lifters 131, the support plates 132 are slidably matched with the limit pins 135 through the arc-shaped guide grooves 134, and the top ends of the support plates 132 are rigidly connected to the movable frame 12. Further, the lifting mechanism also includes a support 136 fixedly connected to the fixed bracket 11, and the support 136 is hinged to the lifters 131.
[0038] See also Figure 5 The screening device for recycling waste porcelain also includes a blockage reminder module 60, which includes a reminder 61, a split contact switch 62 and a power supply 63 connected in series. The two split parts of the split contact switch 62 are respectively installed on the movable frame 12 and the screening member 20, and are in contact under the action of gravity. Specifically, after the broken porcelain left on the screen 22 is dumped by the jacking mechanism, when the screen 22 is blocked by a large number of broken porcelain, the weight of the screening member 20 increases greatly, and the elastic member 14 is over-compressed. At this time, the two split parts of the split contact switch 62 will contact, so that the reminder 61 is energized and a prompt message is issued. The rolling mechanism 30 can be manually opened to clean the broken porcelain blocked on the screen 22, or a controller can be set to issue a command to start the rolling mechanism 30 after receiving the prompt message. The specific controller and the corresponding control circuit adopt the existing technology, so they are not described in detail here.
[0039] In one embodiment, see Figure 3 The elastic member 14 includes an upper connecting member 141 hinged to the sub-screening member 20, a lower connecting member 142 hinged to the movable frame 12, and a spring 143 arranged between the upper connecting member 141 and the lower connecting member 142. In this way, no matter how much the movable frame 12 and the sub-screening body are inclination, the elastic member 14 can maintain a vertical state, reducing the distortion of the spring 143, and can improve the vibration stability of the sub-screening member 20 when the vibration generator 40 is running.
[0040] In one embodiment, see Figure 3 The two parts of the split contact switch 62 are fixedly connected to the upper connecting member 141 and the lower connecting member 142 respectively. In this way, the gravity of the sub-screening member 20 compresses the spring 143, so that the two parts of the split contact switch 62 can be brought closer.
[0041] In one embodiment, a funnel 50 is fixedly provided on the fixed bracket 11 , and the broken porcelain screened by the screening element 20 flows into the funnel 50 and falls into a movable container under the guidance of the funnel 50 .
