Description

Technical Field

[0001] This utility model relates to the field of woven bag thickness detection technology, and more specifically, to a moving thickness detection device for plastic woven bags with rollers. Background Technology

[0002] Plastic woven bags are made from materials such as polyethylene and polypropylene. Due to their lightweight, wear-resistant, and waterproof properties, they are widely used for the storage and transportation of grains, building materials, chemical products, etc.

[0003] Thickness is a core indicator affecting tensile strength, tear strength, and load-bearing capacity. Insufficient thickness can easily lead to breakage and leakage during use, compromising the safety of the contents; excessive thickness, on the other hand, results in material waste and increased production costs. However, current methods for detecting the thickness of plastic woven bags largely rely on manual sampling or simple offline equipment, which cannot achieve continuous online detection during the production process. This is inefficient and prone to missing defective products. The conveyor mechanism is also prone to slippage and misalignment, leading to inaccurate detection positions and difficulty in guaranteeing accuracy. Furthermore, the detection data lacks real-time visualization, making it difficult for operators to adjust production parameters in a timely manner. Utility Model Content

[0010] The technical effects and advantages of this utility model are as follows:

[0011] By combining roller conveyor with the detection chamber design, continuous online detection can be achieved during the movement of woven bags, which greatly improves detection efficiency and avoids the limitations of offline sampling. The double springs and high-precision pressure sensors work together, combined with the arc pad and measuring rod for precise alignment, to eliminate detection deviation and ensure detection accuracy.

[0020] 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.

[0021] This embodiment discloses a plastic woven bag moving thickness detection device with rollers, which aims to realize continuous and accurate thickness detection during the movement of plastic woven bags, and solve the problems of low efficiency and poor stability of detection results in existing detection methods.

[0022] As attached Figure 1 and attached Figure 2 As shown, the testing device includes a vertical plate 1, which serves as the supporting base for the entire device. It is made of high-strength aluminum alloy to ensure structural stability.

[0023] As attached Figure 3 As shown, a support rod 2 is provided on one side of the upright plate 1. A connecting block 11 is integrally formed at the end of the support rod 2 away from the roller 3. The connecting block 11 is detachably installed on the upright plate 1 by two sets of symmetrically distributed bolts, which facilitates subsequent maintenance and disassembly.

[0024] One end of the support rod 2 is rotatably connected to the roller 3 via a pivot. The outer circumference of the roller 3 is provided with an anti-slip rubber layer to prevent slippage during the conveying of plastic woven bags. An arc pad 10 is provided on one side of the roller 3. The arc pad 10 is made of wear-resistant polyurethane material and its shape is adapted to the outer circumference of the roller 3. The arc pad 10 is fixed to the support rod 2 by embedded installation.

[0025] As attached Figure 5 As shown, a limiting frame 4 is provided on one side of the top of the upright plate 1. The limiting frame 4 is a rectangular hollow structure, which is fixedly installed on the top of the connecting block 11 by bolts. A display screen 12 is fixed to the outside of the limiting frame 4 by clips. The display screen 12 is electrically connected to the subsequent pressure sensor 5 and is used to display the detected woven bag thickness data in real time. A pressure sensor 5 for displacement detection is fixedly installed on the top of the limiting frame 4 by screws. This pressure sensor 5 is a high-precision strain gauge pressure sensor.

[0026] As attached Figure 4As shown, a top rod 6 is movably inserted through the middle of the limiting frame 4. A measuring rod 7 is fixed to the bottom end of the top rod 6 via a threaded connection. The bottom end of the measuring rod 7 has a hemispherical structure to reduce wear when in contact with the woven bag. A first spring 8 is sleeved on the outside of the measuring rod 7. The top end of the first spring 8 abuts against the bottom of the limiting frame 4, and the bottom end abuts against the limiting step in the middle of the measuring rod 7. A second spring 9 is sleeved on the top of the top rod 6. The top end of the second spring 9 abuts against the detection end of the pressure sensor 5, and the bottom end abuts against the limiting ring at the top of the top rod 6. Both the first spring 8 and the second spring 9 are made of stainless steel with the same elastic coefficient to ensure consistent reset.

[0027] It is worth noting that, as shown in the attached document... Figure 3 and attached Figure 4 As shown, the arc pad 10 is located directly below the measuring rod 7, and a detection cavity for the woven bag to pass through is formed between the measuring rod 7 and the support rod 2. The initial spacing of the detection cavity can be finely adjusted by adjusting the installation height of the connecting block 11 on the upright plate 1 to adapt to the detection of woven bags with different thickness ranges.

[0028] The specific working principle is as follows: During use, one end of the plastic woven bag to be tested is placed on roller 3. An external traction device drives the woven bag to move along roller 3 towards the detection chamber. The woven bag is smoothly conveyed by roller 3 to the space between the arc pad 10 and the measuring rod 7. When the woven bag passes through the detection chamber, due to the thickness of the woven bag itself, it will generate an upward resisting force on the bottom end of the measuring rod 7, causing the measuring rod 7 to move upward.

[0029] When the measuring rod 7 moves upward, it drives the top rod 6 to move upward synchronously. At this time, the first spring 8 is compressed by the measuring rod 7 and contracts. Simultaneously, the second spring 9 at the top of the top rod 6 is also compressed due to the resistance of the pressure sensor 5. The pressure sensor 5 detects the pressure signal transmitted by the second spring 9. According to Hooke's Law, pressure is proportional to displacement. Combining the elastic coefficients of the first spring 8 and the second spring 9, the pressure signal is converted into the displacement of the measuring rod 7, which is the actual thickness of the plastic woven bag.

[0030] The pressure sensor 5 transmits the converted thickness data to the display screen 12 in real time, which displays the data digitally, enabling continuous thickness detection during the movement of the woven bag. After the woven bag leaves the detection chamber, the first spring 8 and the second spring 9, under the action of elastic restoring force, push the measuring rod 7 and the top rod 6 to reset, preparing for the next detection.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
