[0021] 1.

Specific implementation mode

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0032] Example 1: As Figures 1 to 6 shown, a detection device for plastic woven bag production described in an embodiment of the present invention includes:

[0033] A frame, the frame includes a workbench 1, and a mounting frame 2 is fixed above the workbench 1;

[0034] A detection component, the detection component includes a main body 5 of a laser measuring instrument, and the detection lens 6 of the laser measuring main body is vertically downward for detecting the length or width of a plastic woven bag;

[0035] A driving component, the driving component is used to drive the detection component to move back and forth or left and right relative to the mounting frame 2. The driving component includes a linear module one 3 and a linear module two 4. A pair of linear modules one 3 are provided and fixedly arranged parallel to the lower part of the mounting frame 2. The linear module two 4 is fixed to the bottom of the linear slide of the linear module one 3, and the linear module one 3 is perpendicular to the linear module two 4; the main body 5 of the laser measuring instrument is fixed to the bottom of the linear slide of the linear module two 4;

[0036] A dust removal component, the dust removal component is arranged on the side of the main body 5 of the laser measuring instrument, and the dust attached to the detection lens 6 is cleaned through the dust removal component;

[0037] During operation, first lay the plastic woven bag to be detected flat on the workbench 1. Then start the linear module 1 3. Drive the linear module 2 4 and the laser measurement instrument body 5 below to move left and right through the linear module 1 3. The detection lens 6 includes a transmitting lens and a receiving lens. Emit a laser beam through the detection lens 6. When the laser beam contacts the woven belt, it is reflected, and the reflected light signal is received through the reflection lens, enabling the laser beam to accurately scan the surface of the woven bag. The laser measurement instrument body 5 calculates the distance to the target object based on the time difference or displacement of the reflected light. The path length of the laser moving on the woven bag can be known through the linear module 1 3 and the linear module 2 4, so that the length of the woven bag can be detected according to the path of the laser. Similarly, use the linear module 2 4 to drive the laser detection instrument body to move forward and backward to detect the width of the woven bag, realizing automatic detection. Workers only need to lay the woven bag flat on the workbench 1, reducing the operation difficulty and improving the detection efficiency;

[0038] In addition, by setting up a dust removal component, the dust attached to the detection lens 6 can be cleaned when the detection component is not in use.

[0039] The dust removal component includes a vertical cylinder 10. A disc 11 is fixed in the middle of the vertical cylinder 10. A vertical pipe 13 is rotatably installed in the middle of the disc 11 through a bearing. The bottom end of the vertical pipe 13 is located below the disc 11 and a plurality of driving blades 14 are evenly distributed on the outer wall. The top end of the vertical pipe 13 is located above the disc 11. An activity plate 18 is arranged above the vertical pipe 13. A cleaning brush 19 is installed on the upper surface of the activity plate 18. An air pipe 9 for blowing the driving blades 14 to rotate is fixed on the lower side wall of the vertical cylinder 10. The air pipe 9 is connected to an external dual-function air pump through a hose. An air outlet hole 32 is opened on the upper side wall of the vertical cylinder 10;

[0040] During operation, when the detection component is not needed, align the vertical cylinder 10 with the detection lens 6. Start the dual-function air pump. The air pump discharges air into the vertical cylinder 10 through the air pipe 9. The air pipe 9 is inclined to blow the driving blades 14 and the vertical cylinder 10 to rotate, and then drive the activity plate 18 and the cleaning brush 19 to rotate, so as to clean the dust on the surface of the detection lens 6 through the cleaning brush 19. In addition, a plurality of small holes are opened on the activity plate 18. The small holes are distributed in the gaps between the bristles of the cleaning brush 19. The air flow can enter the upper cavity of the vertical cylinder 10 along the vertical pipe 13 and blow the dust out through the air outlet hole 32 to quickly clean the dust.

[0041] A plurality of through grooves 12 are symmetrically formed in the disc 11, and a thin sheet 22 is provided at the bottom of the through groove 12; during operation, the thin sheet 22 can be unidirectionally opened downward. When the lower part of the vertical cylinder 10 is inflated, the airflow pushes the thin sheet 22 to close the through groove 12. At this time, the airflow can only enter the interior of the vertical cylinder 10 through the vertical pipe 13, so that the airflow diffuses from the middle to the periphery. In this way, not only can the dust be discharged from the air outlet, but also the dust inside the cleaning brush 19 can be cleaned synchronously.

[0042] Symmetrically fixed to the side of the top of the vertical cylinder 10 are support plates 16, and an elastic block 17 is fixed above the support plates 16. The elastic block 17 is designed to be thin-walled and hollow. A through hole 29 is formed at the top of the elastic block 17, and an air inlet hole is formed at the bottom of the elastic block 17. The aperture of the through hole 29 is smaller than the aperture of the air inlet hole.

[0043] A through hole is formed in the disc 11, and a movable rod 24 is slidably installed in the through hole. A circular ring 23 is fixed to the bottom of the movable rod 24.

[0044] A fixed block 25 is fixed to the top of the movable rod 24. The side wall of the fixed block 25 is elastically connected to a movable block 26 through a second spring 31. A side plate 27 is vertically fixed to the end of the movable block 26 away from the fixed block 25, and a plurality of convex blocks 28 are fixed to the inner wall of the side plate 27.

[0045] A first spring 30 is provided between the fixed block 25 and the disc 11.

[0046] During operation, when the vertical cylinder 10 is inflated through the air pipe 9, the airflow enters the interior of the elastic block 17 through the vertical pipe 13 and the air inlet hole, causing the elastic block 17 to expand and become larger. Then, the movable plate 18 and the cleaning brush 19 are pushed upward, so that the cleaning brush 19 can be in full contact with the detection lens 6, facilitating the dust cleaning treatment of the detection lens 6 by the cleaning brush 19; after the cleaning is completed, the dual-functional air pump is controlled to operate in the reverse direction, and the gas inside the vertical cylinder 10 is pumped out. At this time, the gas inside the elastic block 17 is discharged through the vertical pipe 13, so that the volume of the elastic block 17 becomes smaller, and then the movable plate 18 is driven to move downward. During this process, the movable plate 18 contacts the arc surface of the convex block 28, squeezing the side plate 27 to move outward, and the movable plate 18 will vibrate after passing through the convex block 28. As a result, the bristles of the cleaning brush 19 above the movable plate 18 vibrate, further cleaning the dust attached to the bristles; and a negative pressure is generated at the lower part of the vertical cylinder 10, causing the thin sheet 22 to curl downward and open, so as to collect the dust shaken off from the bristles into the lower cavity of the vertical cylinder 10 through the through groove 12, preventing the dust from spreading to the surrounding area.

[0047] In addition, the movable rod 24 and the circular ring 23 are limited by the first spring 30, so that the circular ring 23 is close to the thin sheet 22. When the thin sheet 22 is curled and opened downward, the circular ring 23 supports and limits the thin sheet 22 to prevent the curling angle of the thin sheet 22 from being too large and damaging the thin sheet 22. Moreover, when the movable plate 18 contacts the convex block 28 during the downward movement, a downward pressure can be applied to the convex block 28, and then transmitted to the movable rod 24 through the side plate 27, the movable block 26 and the fixed block 25 to drive the movable rod 24 to move downward. At this time, the first spring 30 is compressed. After the movable plate 18 completely passes the convex block 28, the first spring 30 is released to drive the movable rod 24 to reset. During the process, the bottom circular ring 23 is driven to move up and down, and then the thin sheet 22 is driven to shake up and down by the circular ring 23 to clean the dust attached to the thin sheet 22.

[0048] An activity sleeve 21 is slidably sleeved on the outer wall of the top of the vertical cylinder 10, and the mounting plate 8 supports the activity sleeve 21. A magnetic disk 20 is fixed to the bottom edge of the detection lens 6. The magnetic disk 20 and the activity sleeve 21 are mutually attracted. An L-shaped plate is fixed to the outer wall of the laser measuring instrument main body 5, and a motor 7 for driving the mounting plate 8 to rotate horizontally is fixed on the L-shaped plate.

[0049] During operation, when the detection component needs to be used for detection, the motor 7 is started. The motor 7 drives the mounting plate 8 and the vertical cylinder 10 to rotate, so that the vertical cylinder 10 is misaligned with the detection lens 6, facilitating the use of the detection lens 6 for detection. After the detection work is completed, the motor 7 is used to drive the vertical cylinder 10 to move to directly below the detection lens 6, facilitating the use of the dust removal component to clean the dust on the detection lens 6.

[0050] There is a gap between the top end of the vertical cylinder 10 and the bottom end of the detection lens 6, facilitating the rotation of the vertical cylinder 10 to below the detection lens 6. When the vertical cylinder 10 is aligned with the detection lens 6, the magnetic disk 20 attracts the activity sleeve 21 to move upward, so that the activity sleeve 21 is adsorbed on the bottom of the detection lens 6, and the gap is blocked by the activity sleeve 21. Moreover, the air outlet hole 32 is arranged at a position adjacent to the upper end surface of the mounting plate 8. When the activity sleeve 21 moves upward, the air blowing hole is exposed, facilitating the discharge of internal dust.

[0051] In addition, after the dust cleaning task is completed, the vertical cylinder 10 and the activity sleeve 21 remain below the detection lens 6 to protect the lens and can play a dust-proof effect.

[0052] Embodiment 2: As Figure 3 shown, compared with Embodiment 1, another implementation manner of the present invention is that an end cover 15 is detachably installed at the bottom of the vertical cylinder 10. During operation, the inside of the vertical cylinder 10 can be cleaned by removing the end cover 15.

[0053] Working principle: When it is necessary to use the detection component for detection, start the motor 7. The motor 7 drives the mounting plate 8 and the vertical cylinder 10 to rotate, so that the vertical cylinder 10 is misaligned with the detection lens 6. Then, lay the plastic woven bag to be detected flat on the workbench 1. After that, start the linear module 1 3, and drive the linear module 2 4 and the laser measurement instrument main body 5 below to move left and right through the linear module 1 3. The detection lens 6 includes a transmitting lens and a transmitting lens. Laser beams are emitted through the detection lens 6. When the laser beams contact the woven belt, they are reflected, and the reflected light signals are received through the reflecting lens, so that the laser beams can accurately scan the surface of the woven bag. The laser measurement instrument main body 5 calculates the distance from the target object according to the time difference or displacement of the reflected light. The path length of the laser moving on the woven bag can be known through the linear module 1 3 and the linear module 2 4, so that the length of the woven bag can be detected according to the path of the laser. Similarly, use the linear module 2 4 to drive the laser detection instrument main body to move forward and backward to detect the width of the woven bag, realizing automatic detection. Workers only need to lay the woven bag flat on the workbench 1, which reduces the operation difficulty and improves the detection efficiency;

[0054] After the detection work is completed, drive the vertical cylinder 10 to move to directly below the detection lens 6 through the motor 7, which is convenient for using the dust removal component to clean the dust on the detection lens 6. Start the dual-function air pump. The air pump sends air into the vertical cylinder 10 through the air pipe 9. The air pipe 9 is inclined to blow the driving blade 14 and the vertical cylinder 10 to rotate, and then drive the movable plate 18 and the cleaning brush 19 to rotate, so as to clean the dust on the surface of the detection lens 6 through the cleaning brush 19; in addition, a plurality of small holes are opened on the movable plate 18, and the small holes are distributed in the gaps between the bristles of the cleaning brush 19. The air flow can enter the upper cavity of the vertical cylinder 10 along the vertical pipe 13, and blow the dust out through the air outlet holes 32 to quickly clean the dust;

[0055] When inflating into the vertical cylinder 10 through the air pipe 9, the air flow enters the elastic block 17 through the vertical pipe 13 and the air inlet holes, making the elastic block 17 expand and become larger, and then pushing the movable plate 18 and the cleaning brush 19 to move upward, so that the cleaning brush 19 can be in full contact with the detection lens 6, which is convenient for cleaning the dust on the detection lens 6 through the cleaning brush 19; after the cleaning is completed, control the dual-function air pump to operate in the reverse direction to extract the gas inside the vertical cylinder 10. At this time, the gas inside the elastic block 17 is discharged through the vertical pipe 13, so that the volume of the elastic block 17 becomes smaller, and then drives the movable plate 18 to move downward. During the process, the movable plate 18 contacts the arc surface of the convex block 28, squeezing the side plate 27 to move outward, and the movable plate 18 will vibrate after passing through the convex block 28, so that the bristles of the cleaning brush 19 above the movable plate 18 vibrate, further cleaning the dust attached to the bristles; and a negative pressure is generated in the lower part of the vertical cylinder 10, so that the thin sheet 22 curls downward and opens, so as to collect the dust shaken off from the bristles into the lower cavity of the vertical cylinder 10 through the through groove 12, preventing the dust from spreading to the surrounding;

[0056] In addition, the movable rod 24 and the circular ring 23 are limited by the first spring 30, so that the circular ring 23 is close to the thin sheet 22. When the thin sheet 22 is curled and opened downward, the circular ring 23 supports and limits the thin sheet 22 to prevent the curling angle of the thin sheet 22 from being too large and damaging the thin sheet 22. Moreover, when the movable plate 18 contacts the convex block 28 during the downward movement, a downward pressure can be applied to the convex block 28, and then transmitted to the movable rod 24 through the side plate 27, the movable block 26 and the fixed block 25 to drive the movable rod 24 to move downward. At this time, the first spring 30 is compressed. After the movable plate 18 completely passes the convex block 28, the first spring 30 is released to drive the movable rod 24 to reset. During the process, the bottom circular ring 23 is driven to move up and down, and then the thin sheet 22 is driven to shake up and down by the circular ring 23 to clean the dust attached to the thin sheet 22.

Taking the perspective of the person observing as the standard, the side of the device facing the observer is defined as the front, and the left side of the observer is defined as the left, and so on.
