Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing device technology, specifically to a woven bag sealing device. Background Technology
[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. The weaving density refers to the number of warp and weft yarns in the woven fabric. When a woven bag is filled with materials, a sealing device is needed to seal the bag for packaging.
[0003] The woven bag sealing device described in authorization announcement number CN223015097U includes a base frame, a clamping mechanism above the base frame, and a sealing mechanism located above the clamping mechanism. The sealing mechanism includes a conveying component and a sealing component. Beneficial effects: The conveying component conveys the woven bag, and during conveying, a pulling structure clamps the opening of the woven bag and pulls it towards the sealing point. Simultaneously, while pulling the woven bag, the sealing component presses down on the openings of woven bags of different diameters, aligning the top of the woven bag. By simultaneously pressing down on the opening of the woven bag and sealing it, the automated sealing operation reduces unevenness at the opening of the woven bag, improves the flatness of the sealed woven bag, and enhances the sealing quality. It is suitable for sealing woven bags of different diameters.
[0004] However, existing technologies still have shortcomings: In the prior art, when the opening of the woven bag moves to the front end of the two clamps, the V-shaped structure formed by the front ends of the two clamps compresses the upper diameter of the woven bag, causing the upper end of the woven bag to shrink between the two clamps. However, when the woven bag, which is held by a pneumatic clamp at one end, moves backward with the transmission of the conveyor belt to seal, the upper end of the woven bag is still prone to skewing or wrinkling due to uneven force, affecting the sealing effect of the woven bag.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.
[0026] A woven bag sealing device, such as Figure 1 and 9 As shown, the device includes a fixed frame 1, a conveyor belt 2 mounted on the fixed frame 1, and transmission rollers 3 mounted at both ends inside the conveyor belt 2. The transmission rollers 3 are rotatably connected to the fixed frame 1.

A locking knob 14 for use with the insertion rods 13 is threadedly connected to one side of the fixed column 11. The woven bags filled with materials are placed on the conveyor belt 2. The motor 4 drives the transmission roller 3 to rotate, thereby driving the woven bags on the conveyor belt 2 to move. The limiting plates 12 limit the movement of the bags. The position of the limiting plates 12 can be adjusted by the insertion rods 13, and then the position can be fixed by the locking knob 14.
[0028] like Figure 1 and 3As shown, a support mechanism 5 is provided at one end of the fixed frame. The support mechanism 5 includes a top seat 51 located at one end of the fixed frame 1. A cylinder 52 is fixedly connected to the upper end of the top seat 51. A lifting frame 53 is fixedly connected to the lower end of the cylinder 52. A fixed plate 54 is fixedly connected to the middle of the lower end of the lifting frame 53. Cylinders 55 are fixedly connected to both sides of the fixed plate 54. A slide plate 56 is fixedly connected to one end of the cylinder 55. A support rod 57 is fixedly connected to the lower end of the slide plate 56. A sliding rod 58 is provided at the front and rear of the lower end of the lifting frame 53. The slide plate 56 is slidably sleeved on the sliding rod 58. A support frame 59 is fixedly connected at the front and rear of the lower end of the top seat 51.
[0029] When the woven bag containing materials with its upper opening moves to the lower end of the support rod 57, the first cylinder 52 is activated to move the lifting frame 53 downward, thereby driving the support rod 57 downward to insert into the inside of the woven bag opening. Then, the second cylinder 55 at both ends is activated to drive the sliding plates 56 at both ends to move away from each other, thereby driving the support rods 57 at both ends to move away from each other, thus supporting and flattening the woven bag opening.
[0030] like Figure 6-9 As shown, a clamping mechanism 6 is provided on the fixed frame 1. The clamping mechanism 6 includes a fixed seat 61 fixedly connected to the front and rear of the upper end of the fixed frame 1. A slider 62 is slidably connected inside the fixed seat 61. A bracket 63 is fixedly connected to the upper end of the slider 62. A clamping plate 64 is provided on the side of the bracket 63 that is close to each other. A cylinder 65 is fixedly connected to the middle of the upper front end of the bracket 63. The front end of the cylinder 65 is fixedly connected to the middle of the front end of the front clamping plate 64. Sliding columns 66 are fixedly connected to both sides of the front end of the front clamping plate 64. The sliding columns 66 pass through the bracket 63. A cylinder 67 is fixedly connected to the middle of the upper front end of the rear end bracket 63. The front end of the cylinder 67 is fixedly connected to the middle of the rear end of the rear end clamping plate 64. Telescopic rods 68 are fixedly connected to both sides of the upper front end of the rear end bracket 63. The telescopic rods 68 are fixedly connected to the rear side of the rear end clamping plate 64.
[0031] A threaded rod 9 is rotatably connected inside the fixed base 61. The threaded rod 9 is threaded into the middle of the slider 62. A motor 10 is fixedly connected to one end of the fixed base 61. The output shaft of the motor 10 is fixedly connected to one end of the threaded rod 9.
[0032] After the support rods 57 move away from each other to support and flatten the opening of the woven bag, cylinders 65 and 67 drive the front and rear clamping plates 64 to move closer to each other and move to a set distance to clamp the lower end of the woven bag opening. In this way, the lower end of the woven bag opening can be clamped horizontally and flat. Then, motors 4 and 10 are started simultaneously. Motor 4 drives the conveyor belt 2 to continue moving the woven bag. The front and rear motors 10 drive the threaded rod 9 to rotate, thereby driving the front and rear sliders 62, brackets 63 and conveyor belt 2 to move synchronously. The front and rear clamping plates 64 can clamp the woven bag and move synchronously with it.
[0033] An ultrasonic sealing machine 7 is installed at the rear right end of the fixed frame 1. A sealing mechanism 8 is installed at the front end of the ultrasonic sealing machine 7. The sealing mechanism 8 includes a connecting seat 81 installed at the front end of the ultrasonic sealing machine 7. A rotating shaft 82 is rotatably inserted into the middle of the connecting seat 81. A roller 83 is fixedly sleeved at the lower end of the rotating shaft 82. A metal block 84 is installed behind the roller 83. The metal block 84 is fixedly connected to the front end of the ultrasonic sealing machine 7. A bushing that works with the rotating shaft 82 is fixedly connected at the lower end of the connecting seat 81. A protective cover that is sleeved on the front end of the roller 83 is fixedly connected at the lower end of the bushing.
[0034] An auxiliary plate 85 is fixedly connected to the front end of the ultrasonic sealing machine 7. An L-shaped auxiliary support plate 86 is fixedly connected to the lower end of the connecting seat 81. An inclined guide plate is provided on the left side of the auxiliary support plate 86. A groove 87 for use with a metal block 84 is opened in the middle of the auxiliary plate 85. A groove 88 for use with a roller 83 is opened in the middle of the auxiliary support plate 86. A motor 89 is fixedly connected to the upper end of the connecting seat 81. The lower end of the motor 89 is fixedly connected to the rotating shaft 82.
[0035] When the front and rear clamping plates 64 clamp the woven bag and move synchronously between the auxiliary plate 85 and the auxiliary support plate 86, the upper end of the woven bag opening is limited. This application is suitable for woven bags with a certain degree of support that can stand upright after clamping. At this time, the lower end of the woven bag sealing position is clamped, and the sealing position is limited by the auxiliary plate 85 and the auxiliary support plate 86. When it moves between the roller 83 and the metal block 84 at the front end of the ultrasonic sealing machine 7, the roller 83 rotates to seal the woven bag. The ultrasonic sealing machine 7 converts high-frequency electrical signals (usually above 20kHz) into mechanical vibrations through a transducer. The vibrations are transmitted to the welding head roller 83 and the metal block 84, forming frictional heat, thereby performing heat-melting bonding sealing at the sealing point of the woven bag. The working principle of the ultrasonic sealing machine 7 is existing technology, so it will not be described in detail.
[0036] In specific implementation of this utility model, such as Figure 1-9 As shown, in use, the woven bags filled with materials are placed on the conveyor belt 2. The motor 4 drives the transmission roller 3 to rotate, thereby moving the woven bags on the conveyor belt 2. The limiting plate 12 limits the movement of the bags. The position of the limiting plate 12 can be adjusted back and forth by the plug rod 13, and then the position can be fixed by the locking knob 14.
[0037] When the open woven bag containing materials moves to the lower end of the support rod 57, the conveyor belt stops conveying, and the cylinder 52 is activated to move the lifting frame 53 downward, thereby driving the support rod 57 to move downward and insert into the inside of the woven bag opening. Then, the cylinders 55 at both ends are activated to drive the sliding plates 56 at both ends to move away from each other, thereby driving the support rods 57 at both ends to move away from each other, thus supporting and flattening the woven bag opening.
[0038] After the support rods 57 move away from each other to support and flatten the opening of the woven bag, cylinders 65 and 67 drive the front and rear clamping plates 64 to move closer to each other and move to a set distance to clamp the lower end of the woven bag opening. In this way, the lower end of the woven bag opening can be clamped horizontally and flat. Then, motors 4 and 10 are started simultaneously. Motor 4 drives the conveyor belt 2 to continue moving the woven bag. The front and rear motors 10 drive the threaded rod 9 to rotate, thereby driving the front and rear sliders 62, brackets 63 and conveyor belt 2 to move synchronously. The front and rear clamping plates 64 can clamp the woven bag and move synchronously with it.
[0039] When the front and rear clamping plates 64 clamp the woven bag and move synchronously between the auxiliary plate 85 and the auxiliary support plate 86, the upper end of the woven bag opening is limited. This application is suitable for woven bags with a certain degree of support that can stand upright after clamping. At this time, the lower end of the woven bag sealing position is clamped, and the sealing position is limited by the auxiliary plate 85 and the auxiliary support plate 86. When it moves between the roller 83 and the metal block 84 at the front end of the ultrasonic sealing machine 7, the roller 83 rotates to seal the woven bag. The ultrasonic sealing machine 7 converts the high-frequency electrical signal (usually above 20kHz) into mechanical vibration through the transducer. The vibration is transmitted to the welding head roller 83 and the metal block 84 to form frictional heat, thereby performing heat-melting bonding sealing at the sealing point of the woven bag.
[0040] In this device, the woven bag is opened and flattened by the support rods 57 at both ends. Then, the lower end of the sealing position is horizontally clamped by the clamping plates 64 at the front and rear ends, which can ensure the flatness of the lower end of the sealing position. At the same time, the sealing position is limited by the auxiliary plate 85 and the auxiliary support plate 86, which further ensures the flatness of the sealing position, making the sealing position flatter and more aesthetically pleasing.
[0041] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
