Description

Technical Field

[0001] The utility model relates to the technical field of glass production, and in particular to a paper scrap removal device for a cutting knife of a Mini LED back panel glass paper laying machine. Background Art

[0002] In the glass production process, the paper laying accuracy of the cold end paper laying machine is particularly important, and the paper laying efficiency of the paper laying machine directly affects the glass output of the entire production line. Chinese invention patent CN116281176A discloses an automatic paper-changing paper laying machine. When the glass plate is running, the paper driving roller drives the paper to run synchronously with the glass plate, and the paper is attached to the glass plate under the action of static electricity. In the actual production process, the failure of the paper driving wheel is one of the very important influencing factors. In the long-term analysis of the cause of the failure, the paper scraps stuck under the paper driving wheel cause the paper driving wheel to slip, which will directly affect the control of the paper feeding length accuracy. At this stage, when such a situation occurs, it is necessary to switch the paper laying machine to the standby machine, and then clean the paper scraps under the faulty paper driving wheel, and then wipe it with alcohol. Because the cutting knife is close to the paper driving wheel, more paper scraps are generated every day, so the frequency of paper driving wheel failure is also high. Therefore, it is necessary to develop a paper scrap removal device to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 1 , 3 As shown, this embodiment provides a Mini LED backplane glass paper laying machine cutting knife paper scrap removal device, including a chip collection bin 1, the chip collection bin 1 is provided with a chip feed port 101, the chip feed port 101 is located at the paper laying machine cutting knife and extends along the length direction of the cutting knife, the width of the chip feed port 101 is greater than the cutting knife, so that all the paper scraps generated when the cutting knife cuts paper can be sucked into the chip collection bin 1. An exhaust port is provided at one end of the chip collection bin 1, and a filter element 2 is provided at the exhaust port inside the chip collection bin 1, and an exhaust fan 301 is provided outside the chip collection bin 1, and the exhaust fan 301 is driven by a motor three 302. The motor three 302 drives the exhaust fan 301 to rotate, and a negative pressure space is generated in the chip collection bin 1. The chip collection bin 1 generates a pressure difference at the chip feed port 101, and the paper scraps generated by the cutting knife are sucked in through the chip feed port 101.

[0022] like Figure 1 As shown, a driving wheel 401 and a driven wheel 402 are arranged at both ends of the chip collection bin 1, the driving wheel 401 is driven to rotate by a motor 1, a chain 403 is arranged on the driving wheel 401 and the driven wheel 402, a chip sweeping mechanism 5 is arranged at the bottom of the chain 403, and chip outlets 102 are arranged on the chip collection bin 1 corresponding to the driving wheel 401 and the driven wheel 402, respectively, and a gate valve 6 is arranged at the chip outlet 102. The chip sweeping mechanism 5 sweeps the paper scraps sucked into the chip collection bin 1 out of the chip collection bin 1 through the chip outlet 102 for unified collection and treatment. Specifically, as shown in FIG. Figure 2 As shown, the chip sweeping mechanism 5 includes a long rubber fixed block 501 arranged at the bottom of the chain 403. The fixed block 501 extends along the width direction of the chip bin 1 to ensure that when the fixed block 501 moves along the length direction of the chip bin 1 driven by the chain 403, the paper scraps in the chip bin 1 can be swept away. A brush 502 is arranged at the bottom of the fixed block 501. When the fixed block 501 moves, the brush 502 brushes the paper scraps in the chip bin 1 to the chip outlet 102. Figure 4As shown, the gate valve 6 includes a support plate 605, the support plate 605 is fixed at the chip outlet 102, a second motor 604 is arranged on the support plate 605, the output shaft of the second motor 604 is connected to a reducer 603, the output shaft of the reducer 603 is connected to a screw 602, a gate 601 is fixedly connected to the screw 602, and the gate 601 extends into the chip outlet 102. When the chip sweeping mechanism 5 sweeps the paper scraps to the chip outlet 102, the second motor 604 and the reducer 603 drive the gate 601 to rotate 90 degrees, thereby opening the chip outlet 102 and discharging the paper scraps.

[0023] In addition, if Figure 1-2 As shown, a limit switch 8 is provided at the chip outlet 102 in the chip collecting bin 1. When the fixed block 501 of the chip sweeping mechanism 5 moves to the chip outlet 102, it touches the limit switch 8. At this time, the control system controls the starting motor 2 604 according to the signal feedback from the limit switch 8, and finally drives the gate plate 601 in the chip outlet 102 to rotate 90°, thereby discharging the paper scraps swept to the chip outlet 102.

[0024] Working principle:

[0025] When using a paper laying machine to lay paper on glass, it is necessary to cut the paper with a cutting knife, and the cut paper is laid on the glass surface. When the cutting knife cuts the paper, paper scraps are generated. Therefore, the control system starts the motor three 302, and the exhaust fan 301 is used to form a negative pressure in the chip collecting bin 1. The paper scraps generated by the cutting knife are sucked into the chip collecting bin 1 through the chip inlet 101. Large paper scraps directly enter the space of the chip collecting bin 1, and small powdery paper scraps are adsorbed on the surface of the filter element 2 inside the chip collecting bin 1. The filter screen on the filter element 2 is made of sheet non-woven fabric, which can increase the filtering area of ​​paper scraps and dust. At the same time, start the motor one to drive the chip sweeping mechanism 5 at the bottom of the chain 403 to move back and forth between the two chip outlets 102 of the chip collecting bin 1. During this process, the bristles 502 at the bottom of the fixed block 501 sweep the paper scraps to the chip outlet 102, and the fixed block 501 touches the limit switch 8. At this time, the motor 2 604 is started to drive the gate plate 601 to rotate 90° in the chip outlet 102, opening the chip outlet 102. The paper scraps can fall through the chip outlet 102 into the collection bucket below for unified collection and processing.

[0026] Example 2

[0027] On the basis of Example 1, Figure 1 As shown, a compressed air pipe 701 is provided at the air outlet of the dust collecting bin 1, and the compressed air pipe 701 extends into the filter element 2 and a solenoid valve 702 is provided on the compressed air pipe 701. After the device absorbs paper scraps for 10 minutes, the air is sucked out, and the control system opens the solenoid valve 702 to pass 6Mpa compressed air into the dust collecting bin 1, causing the filter element 2 to vibrate, thereby shaking the paper scraps and dust on the surface of the filter screen to the bottom of the dust collecting bin 1, making it easier to remove the paper scraps.
