Description

Technical Field

[0001] This utility model relates to the field of PE fabric production technology, and in particular to a roller for online monitoring of PE fabric thickness. Background Technology

[0002] PE cloth, or polyethylene cloth, is a plastic cloth made from polyethylene resin through processes such as drawing and weaving. It is lightweight, waterproof, acid and alkali resistant, and corrosion resistant. It is relatively inexpensive and durable, and is widely used in agriculture (such as mulching film), industry (such as packaging materials), and daily life (such as rainproof cloth). It is a common plastic product.

[0003] A search revealed that the document with publication number "CN217058763U" states that "this utility model relates to the field of measuring equipment technology, specifically disclosing a geotextile thickness gauge, including a base plate, a measuring mechanism for measuring the thickness of geotextile and adjustment units installed at the four corners of the base plate. The adjustment unit includes a base, two support rods, a rotating shaft, a turntable, a support column, a sleeve, a top rod, and a block. One end of each of the two support rods is fixedly connected to the base, and the other end of each of the two support rods is fixedly connected to the sleeve. One end of the rotating shaft is fixedly connected to the center of the base, and the other end of the rotating shaft is rotatably connected to the turntable. One end of the support column is fixedly connected to the center of the turntable, and the other end of the support column is inserted into the inside of the sleeve. The support column has an inclined surface, and one end of the top rod contacts the inclined surface. The other end of the top rod passes through the top of the sleeve and is fixedly connected to the block." During use, this structural design ensures that the entire instrument is horizontal, guaranteeing uniform stress on the geotextile and preventing any impact on measurement accuracy.

[0004] However, precise control of PE fabric thickness is crucial in the production process, directly affecting product quality and application performance. Traditional PE fabric thickness detection methods often employ offline sampling, which suffers from drawbacks such as untimely detection, low efficiency, and inability to provide real-time feedback for production adjustments. With technological advancements, online monitoring devices have gradually been adopted. However, some existing monitoring devices suffer from insufficient monitoring accuracy and insensitive response to changes in PE fabric thickness. Furthermore, some devices based on mechanical pressure sensing are limited by their mechanical structure, making it difficult to accurately capture thickness information when the PE fabric is running at high speed or experiencing significant thickness variations. Additionally, some optical detection devices, while highly accurate, are easily affected by ambient light, impurities on the PE fabric surface, and other factors, leading to unstable detection results.

[0005] Therefore, we provide a PE fabric thickness online monitoring roller to solve the above problems. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model uses a PE fabric thickness monitoring component. When needed, the sensing roller is in close contact with the surface of the PE fabric and its position is finely adjusted according to the change in fabric thickness. The precise data is fed back to the rotary encoder to ensure that the central control sensor obtains accurate thickness information in real time. At this time, the rotary encoder collects the rotation of the sensing roller caused by the change in PE fabric thickness, which is caused by the rotation of the rear shaft along the rear support bearing through the rotating shaft arm. Based on the rotation angle of the rear shaft, the rotary encoder collects data in real time and transmits it to the central control sensor. The central control sensor calculates the real-time thickness of the PE fabric through a built-in algorithm to ensure monitoring accuracy.

[0022] 2. This utility model uses a PE cloth thickness monitoring component. The driven shaft frame is tightly fixed to the inner side of the upper base through a slot. When the thickness of the PE cloth changes, the sensing roller will not only change through the rotation of the shaft arm, but will also be pushed upward. The driven shaft frame, in conjunction with the upper base, will perform a certain degree of vertical displacement. The driven shaft frame, through its own shaft connection, can avoid the driven shaft frame from rotating with the rotation of the roller shaft. When the sensing roller is subjected to the convex and concave surfaces of the PE cloth, the left and right sets of force damping will be slightly compressed or stretched respectively, and the spring will deform accordingly. The damping deformation sensor captures the deformation data in real time and transmits it to the main control sensor, thereby accurately capturing the thickness change at both ends of the PE cloth and ensuring the uniformity of the overall thickness of the PE cloth during the production process.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 As shown, this utility model provides a technical solution: a PE fabric thickness online monitoring roller, including a lower base 1, a PE fabric bearing assembly 2 installed in the middle of the lower base 1, a central control sensor 3 arranged on the outer side of the lower base 1, and a PE fabric thickness monitoring assembly 4 arranged above the lower base 1. The PE fabric thickness monitoring assembly 4 includes an upper base 401, which is arranged on the upper side of the lower base 1. A rear support rod 402 is welded to the rear side of the upper base 401, and a rear support rod 402 is welded to the end of the rear support rod 402. A rear support bearing 403 is provided, and a rear rotating shaft 404 is installed on the inner side of the rear support bearing 403. A rotating shaft arm 405 is welded to the front side of the outer end of the rear rotating shaft 404. A rotary encoder 406 is connected to the outer side of the rear rotating shaft 404. A roller shaft 407 is connected to the end of the rotating shaft arm 405. A driven shaft bracket 409 is installed at both ends of the roller shaft 407. A force damping device 410 is installed on the inner side of the upper base 401. A damping deformation sensor 412 is installed on the upper side of the upper base 401.

[0030] Furthermore, the PE fabric support assembly 2 includes a support roller 201 installed in the middle of the lower base 1. The surface of the support roller 201 is coated with an enamel layer 202. When the PE fabric passes through the support roller 201, the enamel layer 202 can reduce friction and ensure smooth fabric transmission. Even if friction occurs, the support roller 201 can still rotate, thereby reducing the damage to the PE fabric caused by hard friction.

[0031] Furthermore, the inner wall of the rear rotating shaft 404 is welded to the inner wall of the rear support bearing 403. The end of the rear rotating shaft 404 is connected to the rotary encoder 406. The rotary encoder 406 is electrically connected to the master control sensor 3. When needed, the rotary encoder 406 collects data in real time on the rotation of the rear rotating shaft 404 along the rear support bearing 403 caused by the change in the thickness of the PE cloth due to the sensing roller 408. Based on the rotation angle of the rear rotating shaft 404, the rotary encoder 406 collects data in real time and transmits it to the master control sensor 3. The master control sensor 3 calculates the real-time thickness of the PE cloth through a built-in algorithm to ensure monitoring accuracy.

[0032] Furthermore, a sensing roller 408 is mounted on the surface of the roller shaft 407. The roller shaft 407 is connected to the rotating shaft arm 405 by a bearing. The roller shaft 407 rotates along the rear support bearing 403 via the rotating shaft arm 405 and the rear rotating shaft 404. When needed, the sensing roller 408 is in close contact with the PE fabric surface and its position is finely adjusted according to the change in fabric thickness. The precise data is fed back to the rotary encoder 406 to ensure that the master control sensor 3 obtains accurate thickness information in real time and optimizes the production process.

[0033] Furthermore, the inner wall of the driven shaft bracket 409 is welded to the roller shaft 407, and the driven shaft bracket 409 is connected to the inner side of the upper base 401 by a slot. The driven shaft bracket 409 is arranged in two symmetrical sets on the left and right. When needed, the driven shaft bracket 409 is tightly fixed to the inner side of the upper base 401 through the slot. When the thickness of the PE cloth changes, the sensing roller 408 will not only change through the rotating shaft arm 405, but will also be pushed upward. The driven shaft bracket 409 will cooperate with the upper base 401 to perform a certain degree of vertical displacement. Through its own shaft connection, the driven shaft bracket 409 can avoid the situation where the driven shaft bracket 409 rotates with the rotation of the roller shaft 407.

[0034] Furthermore, the force damping 410 is welded to the driven shaft frame 409. The force damping 410 is arranged in two symmetrical sets. Springs 411 are sleeved on the surface of the force damping 410. The force damping 410 is electrically connected to the damping deformation sensor 412. The damping deformation sensor 412 is electrically connected to the main control sensor 3. When the sensing roller 408 is subjected to the uneven surface of the PE cloth, the left and right sets of force damping 410 will be slightly compressed or stretched respectively. The springs 411 will deform accordingly. The damping deformation sensor 412 captures the deformation data in real time and transmits it to the main control sensor 3, thereby accurately capturing the thickness change at both ends of the PE cloth and ensuring the uniformity of the overall thickness of the PE cloth during the production process.

[0035] Furthermore, a laser scanning probe 5 is installed on the rear side of the lower base 1, and a laser data processor 6 is installed on the outside of the laser scanning probe 5. The laser data processor 6 is electrically connected to the master control sensor 3. When needed, the laser scanning probe 5 will scan the surface of the PE cloth from the lower end of the PE cloth to observe whether there are holes on the surface of the PE cloth and what the probability of them is. The laser data processor 6 analyzes the scanning results in real time and feeds the data back to the master control sensor 3 so as to adjust the production parameters in time and reduce the production of defective products.

[0036] Working Principle: When needed, the lower base 1 and upper base 401 are installed outside the equipment before the PE cloth production roll. As the cloth passes between the support roller 201 and the sensing roller 408, the downward pressure generated by the sensing roller 408 presses the PE cloth against the surface of the enamel layer 202 outside the support roller 201. As the PE cloth is pulled out and rolled up, it drives the sensing roller 408 to rotate through the roller shaft 407, and simultaneously drives the support roller 201 to rotate. As the sensing roller 408 rotates, when the thickness of the PE cloth changes, the sensing roller 408 will undergo a slight displacement. At this time, the roller shaft 407 drives the rear rotating shaft 404 to rotate along the rear support bearing 403 through the rotating shaft arm 405. Thus, the rear rotating shaft 404 drives the rotary encoder 406 to change angle according to the rotation. When the encoder 406 changes angle, the master control sensor 3 calculates the real-time thickness of the PE fabric using a built-in algorithm. Simultaneously, when the sensing roller 408 undulates, the driven shafts 409 at both ends of the roller shaft 407 will slightly float up and down along the inner side of the upper base 401. According to the fluctuation range of the thickness change at both ends of the PE fabric, the force damping 410 at both ends will float to different degrees, and the spring 411 will play a reset role. The fluctuation change of the force damping 410 will transmit the data to the master control sensor 3 through the damping deformation sensor 412, thereby calculating the thickness data of both ends of the PE fabric. At the same time, the laser scanning probe 5 will scan the surface of the PE fabric from bottom to top, meticulously capturing every tiny hole, and transmit the data to the master control sensor 3 through the laser data processor 6. This completes the use process of a PE fabric thickness online monitoring roller.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
