Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag flat dimension detection technology, and more specifically, to a plastic woven bag flat dimension detection device. Background Technology

[0002] Plastic woven bags are mainly made of polypropylene or polyethylene and are classified by sewing method into sewn-bottom bags and sewn-side-bottom bags. They are currently widely used as packaging materials for fertilizers, chemical products, and other items. The main production process involves extruding plastic raw materials into film, cutting, and unidirectionally stretching them into flat yarns, which are then woven together to form the product, commonly known as a woven bag. In the production process of plastic woven bags, the inspection of their flat dimensions is a crucial step in ensuring product quality. Accurate dimensions ensure that the plastic woven bags meet the requirements for loading and transportation during subsequent use. However, the current traditional methods for inspecting the dimensions of plastic woven bags have many problems.

[0003] Existing testing methods mostly rely on manual operation, with inspectors using simple tools such as measuring tapes to measure plastic woven bags. This method is not only inefficient and difficult to meet the testing needs of large-scale production, but also the measurement results are greatly affected by human factors, resulting in large measurement errors and failing to guarantee the accuracy and consistency of the testing. In addition, it is difficult to ensure that the plastic woven bags are in a completely flat state during manual measurement; wrinkles, bends, and other conditions can lead to inaccurate measurement results. Therefore, a device for detecting the flatness dimensions of plastic woven bags is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for detecting the flat dimensions of plastic woven bags, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic woven bag flat size detection device, including a workbench, a movable plate at one end of the workbench, movable wheels symmetrically fixedly connected to both sides of the bottom of the movable plate to facilitate stable movement of the movable plate, a clamping through hole in the middle of the movable plate, a clamping pressure plate at the top of the inner cavity of the clamping through hole, a ruler plate fixedly connected to one side of the clamping pressure plate, and a smoothing mechanism at the top of the workbench, which can smooth the plastic bag placed on the top of the workbench to improve the accuracy of measurement;

[0006] The top of the clamping plate is fixedly connected to multiple first stabilizing rods. A first spring is sleeved in the middle of the first stabilizing rod. A positioning groove is opened on one side of one of the first stabilizing rods. A first threaded rod is inserted into the top side of the moving plate. One end of the first threaded rod is rotatably connected to a squeezing plate. The other end of the first threaded rod is fixedly connected to a turntable. The clamping plate is pushed by the first spring, so that the clamping plate generates downward pressure, which facilitates clamping one end of the plastic bag. By pulling the limiting plate, the first stabilizing rod is controlled to drive the clamping plate to move upward. The turntable is rotated to control the squeezing plate to insert into the positioning groove to fix the first stabilizing rod. This can realize the fixation of the clamping plate, which makes it convenient to place one end of the plastic bag in the middle of the clamping through hole for clamping.

[0007] The worktable has symmetrically arranged first limiting grooves on both sides. A second threaded rod is provided in the middle of the first limiting groove. A synchronous belt is sleeved on one end of the second threaded rod. One end of the second threaded rod is connected to a motor. Stable side plates are symmetrically arranged on both sides of the worktable. A limiting slider is fixedly connected to one end of the stable side plate. By starting the motor, the second threaded rod is controlled to drive the limiting slider to slide inside the first limiting groove. This can control the stable side plate to drive the clamping through hole to move on one side of the worktable, which is convenient for driving.

[0008] Preferably, the extrusion plate corresponds to the positioning groove, one end of the extrusion plate extends into the interior of the corresponding positioning groove, one side wall of the inner cavity of the positioning groove is set as an inclined surface, the first spring is set at the top of the clamping pressure plate, and the top end of the first stabilizing rod extends to the top of the moving plate and is fixedly connected to the limiting plate.

By using the ruler plate instead of the scale, the width of the plastic bag can be detected when the clamping pressure plate clamps one end of the plastic bag after it has been unfolded, and the length of the plastic bag can be detected by the scale on one side of the stabilizing side plate.

[0010] Preferably, the limiting slider is disposed in the middle of the first limiting groove, the second threaded rod passes through the middle of the limiting slider and is threadedly connected to the inner cavity of the limiting slider, a protective box is fixedly connected to one end of the worktable, the synchronous belt is disposed in the middle of the protective box, and the motor is fixed on one side of the protective box. The protective box protects the synchronous belt, and the motor can easily drive the second threaded rod to move the limiting slider inside the first limiting groove, which is convenient for driving and use.

[0011] Preferably, the smoothing mechanism includes a support frame fixed to the top of the workbench near one end of the movable plate, a lifting frame is provided in the middle of the support frame, an electric push rod is fixedly connected to the top of the support frame, the output end of the electric push rod is fixedly connected to the top wall of the lifting frame, a smoothing roller is rotatably connected to the bottom of the lifting frame, a pointer is provided on the top edge of the workbench, an identification sensor is provided on one side of the support frame, and the connecting line between the pointer and the identification sensor is parallel to the support frame.

The top of the third threaded rod passes through the middle of the limiting sliding hole and is fitted with a nut. By activating the electric push rod to control the lifting frame to drive the smoothing roller to move downward, the plastic bag can be smoothed when the moving plate moves and pulls the plastic bag. The protective pad squeezes and guides the plastic bag, which can flatten the bent parts on both sides of the plastic bag, improve the smoothing effect, effectively eliminate wrinkles and bends on the surface of the plastic woven bag, and make it in a completely flat state, ensuring the accuracy of the detection dimensions. By squeezing the third stabilizing rod with the nut, the opening angle of the unfolding inclined plate can be adjusted and fixed.

[0016] 1. This utility model firstly facilitates the flattening of one end of a plastic bag by using a clamping through hole. The first spring pushes the clamping pressure plate to clamp and fix one end of the flattened plastic bag, making it easy to read the width value of the plastic bag through the scale lines on the ruler surface, thus realizing the detection of the width dimension of the plastic bag. By starting the motor, the moving plate is controlled to move the plastic bag away from the worktable until the recognition sensor detects the other end of the plastic bag. At this time, the length value of the plastic bag can be read by the scale lines on the stable side plate surface and the pointer, thus realizing the detection of the flattened dimension of the plastic bag. At the same time, the smoothing mechanism can keep the plastic woven bag in a completely flat state, effectively reducing measurement errors and improving the accuracy of the detection results.

[0017] 2. This utility model also controls the first threaded rod to drive one end of the extrusion plate into the positioning groove by rotating the turntable, which can fix the position of the first stabilizing rod, thereby fixing the position of the clamping pressure plate when placing the plastic bag, which is convenient to use. At the same time, the protective pad can guide the extrusion of the plastic bag, which can flatten the bent parts on both sides of the plastic bag and improve the smoothing effect. Furthermore, by controlling the third threaded rod to slide in the middle of the limiting slide hole and the second limiting slide groove, the tilt angle of the protective pad and the unfolding inclined plate can be adjusted, thereby adjusting the smoothing effect.

[0033] Then, start motor 18 to control moving plate 2 to move plastic bag away from workbench 1 until recognition sensor 24 recognizes the other end of plastic bag. At this time, motor 18 stops automatically. At this time, the length of plastic bag can be read by the scale line on the surface of stable side plate 13 and the pointer, so as to realize the detection of the flat size of plastic bag.

[0034] When the moving plate 2 pulls the plastic bag, the electric push rod 26 is activated to control the smoothing roller 27 and the protective pad 31 to squeeze the plastic bag. At this time, the plastic bag can be flattened when pulled, which improves the accuracy of detection.
