Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag flattening detection technology, and in particular to a plastic woven fabric flattening all-round detection device. Background Technology

[0002] Woven fabric is an item made from polypropylene and polyethylene flat yarns, which are woven together by interlacing the warp and weft threads. This type of fabric is widely used for reinforcement in civil engineering projects, primarily for strengthening and reinforcing, and also provides planar insulation and protection. Unlike non-woven fabrics, it does not have a filtering function.

[0003] After the plastic woven fabric is cut, it needs to be flattened again. This is mainly to address the problem that the mechanical cutting stress and the shrinkage characteristics of the material itself during the cutting process can easily lead to edge curling, local wrinkles, or a decrease in flatness, which affects the product's appearance and its compatibility with subsequent processing.

[0004] However, when the cut plastic woven fabric is flattened, problems such as holes and broken threads on the original surface of the plastic woven fabric will be exposed. Because the stress is released during the flattening process, the originally hidden defects become obvious. Therefore, it is necessary to conduct a comprehensive inspection of the plastic woven bags in order to separate the defective products in the future. In view of this, this application proposes a plastic woven fabric flattening all-round inspection device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] This utility model provides a technical solution: such as Figure 1-6As shown, a plastic woven fabric flattening all-around detection device includes a conveyor frame 1, a conveyor belt 2 rotatably connected to the top surface of the conveyor frame 1, and the drive source of the conveyor belt 2 is driven by an external drive source.

The two adjusting frames 3 are provided with an adjusting mechanism, and the adjusting mechanism adjusts the height of the pressure roller 11. An annular cavity 12 is opened in the pressure roller 11, and multiple heating rods 13 are symmetrically arranged around the annular cavity 12. The heating rods 13 facilitate heat treatment of the flattened plastic woven fabric to prevent it from resetting and warping again. At the same time, the adjustable height of the pressure roller 11 facilitates the flattening of plastic woven fabrics of different thicknesses.

[0025] A detection bracket 4 is fixedly installed on the top surface of the conveyor frame 1. Two lead screw sleeves 18 are slidably connected to the bottom surface of the detection bracket 4. A drive mechanism is provided on the bottom surface of the detection bracket 4, and the drive mechanism drives the two lead screw sleeves 18 to slide back and forth alternately. A detection sensor 22 is fixedly installed on the bottom surface of each lead screw sleeve 18. Multiple nozzles 23 are fixedly connected to the bottom surface of each lead screw sleeve 18. A spraying mechanism is provided on the top surface of the detection bracket 4, and each lead screw sleeve 18 is connected to the spraying mechanism.

[0026] It should be noted that the detection sensor 22 is a mature existing technology, mainly used to detect defects on the surface of woven fabric. At the same time, the defect can be marked by the spraying mechanism through the spray nozzle 23, which facilitates subsequent manual processing. The two detection sensors 22 slide back and forth in an alternating manner to avoid detection blind spots and facilitate comprehensive detection.

[0027] A pusher frame 5 is fixedly installed on the top surface of the conveyor frame 1, and a material distribution mechanism is provided on the bottom surface of the pusher frame 5.

[0028] Furthermore, the spraying mechanism includes a paint tank 14, which is fixedly installed on the top surface of the testing bracket 4. Water pumps 17 are fixed and connected to both outer sides of the testing bracket 4. The outer side of each water pump 17 is connected to the corresponding lead screw sleeve 18 through a connecting pipe 21. Each connecting pipe 21 is a retractable flexible hose. It should be noted that the connecting pipe 21 does not have a specific length to ensure that it can be connected to the water pump 17 during the movement of the lead screw sleeve 18.

[0029] Furthermore, the drive mechanism includes two reciprocating lead screws 20, which are rotatably connected to the inner wall of the detection bracket 4. Each reciprocating lead screw 20 is threadedly connected to a corresponding lead screw sleeve 18. One end of each reciprocating lead screw 20 passes through the detection bracket 4 and is equipped with a gear 19. The two gears 19 mesh with each other, and the two reciprocating lead screws 20 are reversed through the two gears 19, thereby facilitating the staggered reciprocating sliding of the two lead screw sleeves 18.

[0030] Furthermore, the adjustment mechanism includes a threaded rod 6, which is rotatably connected to the bottom surface of one of the adjustment frames 3. A limit rod 28 is fixedly installed on the bottom surface of the other adjustment frame 3. A threaded sleeve 8 is threadedly connected to the threaded rod 6. A U-shaped plate 9 is fixedly installed on the outer side of the threaded sleeve 8. A pressure roller 11 is rotatably connected to the side wall of the U-shaped plate 9. The limit rod 28 is slidably connected to the U-shaped plate 9. A first motor 10 is fixedly installed on the outer side of the U-shaped plate 9. The output shaft of the first motor 10 is coaxially connected to the pressure roller 11. A rocker arm 7 is installed at the top of the threaded rod 6 for easy manual adjustment by the user.

[0031] Furthermore, the material distribution mechanism includes an electric linear guide 25, which is fixedly installed on the top wall of the pusher frame 5. A sliding rod 26 is slidably connected to the bottom surface of the electric linear guide 25, and a push plate 27 is fixedly installed at the bottom end of the sliding rod 26. Openings 24 are provided on both outer sides of the conveyor frame 1, and the top surface of each opening 24 is flush with the top surface of the conveyor belt 2. It should be noted that the electric linear guide 25 is electrically driven and can drive the sliding rod 26 to slide linearly.

[0032] Furthermore, two limiting grooves 16 are symmetrically opened on the top surface of the detection bracket 4, and each lead screw sleeve 18 is slidably connected to the corresponding limiting groove 16. A second motor 15 is fixedly installed on the outside of the detection bracket 4, and the output shaft of the second motor 15 is connected to one of the reciprocating lead screws 20.

[0033] This utility model provides a plastic woven fabric flattening all-round detection device. The specific working principle is as follows: The user places the cut woven fabric at equal intervals on the conveyor belt 2 for transportation through an external device or manually. At the same time, the user can manually turn the rocker arm 7 to drive the threaded rod 6 to rotate, thereby driving the threaded sleeve 8 to slide up and down to adjust the pressure roller 11 and its height. Then, when the woven fabric is transported, it is rolled by the pressure roller 11 to achieve flattening. In addition, multiple heating rods 13 installed in the pressure roller 11 conduct heat to the pressure roller 11, which facilitates the hot rolling of the woven fabric by the pressure roller 11, thereby preventing the woven fabric from curling up after flattening.

[0034] Then, the second motor 15 can be started to drive one of the reciprocating screws 20 to rotate. Through the cooperation of two gears 19, the other reciprocating screw 20 is rotated in the opposite direction. Thus, under the limit of the limit groove 16, the two screw sleeves 18 slide back and forth alternately. At the same time, when the detection sensor 22 detects a defect on the surface of the woven fabric, the electrical signal is transmitted to the controller of the water pump 17, and the water pump 17 is started to draw the paint in the paint tank 14. Then, the paint is sprayed on the defect of the woven fabric through the nozzle 23, which is convenient for the user to handle later.

[0035] Then, the sliding rod 26 can be driven to slide by the electric linear guide 25 and pushed by the push plate 27, so that the woven fabric with surface defects can be transported to the outside through the opening 24.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
