Technical Field

[0001] This utility model relates to the field of sealing technology for bagged liquid seasonings, specifically to a sealing device for bagged liquid seasonings. Background Technology

[0002] A sealing machine is a machine that seals containers containing products. After products are put into packaging containers, in order to preserve the products, maintain their quality, and prevent product loss, the containers need to be sealed. This operation is completed by a sealing machine.

[0003] When packaging bagged liquid seasonings, sealing machines are often used. However, when workers use sealing machines to seal bagged liquid seasonings, it is inconvenient to guide and limit the operation of the packaging bag during placement, which leads to the sealing line not aligning with the bag edge during the subsequent sealing process, thus affecting the sealing quality. Therefore, a sealing device for bagged liquid seasonings has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a sealing device for bagged liquid condiments. Workers can use a transmission structure to drive the first moving plate and the second moving plate to move in opposite directions or away from each other, thereby adapting to bagged condiments of different widths and ensuring that the packaging bag remains centered and does not shift during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing device for bagged liquid seasonings, comprising a body and a support frame. A first fixing plate and a second fixing plate are fixedly connected to the upper and lower sides of both sides of the support frame, respectively.

[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] Please see Figure 1-6 As shown, the sealing device for bagged liquid seasonings includes a body 1 and a support frame 2. A first fixing plate 3 and a second fixing plate 11 are fixedly connected to the upper and lower sides of both sides of the support frame 2, respectively. A support plate 9 is fixedly connected to the front of the first fixing plates 3 on both sides. A first roller 4 is rotatably connected between the first fixing plates 3 on both sides. A first limiting plate 5 is movably connected to both sides of the surface of the first roller 4. A first moving plate 6 is fixedly connected to the front of the first limiting plate 5. A transmission structure 7 for driving the first limiting plate 5 to move is provided between the first moving plates 6 on both sides. A second roller 12 is rotatably connected between the second fixing plates 11 on both sides. A second limiting plate 13 is movably connected to both sides of the surface of the second roller 12. A second moving plate 14 is fixedly connected to the rear of the second limiting plate 13. A connecting plate 15 is fixedly connected between the first moving plate 6 and the second moving plate 14. A buffer structure 16 is provided at the bottom of the body 1.

[0022] The transmission structure 7 includes a bidirectional screw 71, a worm gear 72, and a worm 73. The two ends of the bidirectional screw 71 are rotatably connected to the inside of the support plate 9. The bidirectional screw 71 is internally threaded to the first moving plates 6 on both sides 7. The worm gear 72 is fixedly connected to the surface of the bidirectional screw 71. The worm 73 meshes with the worm gear 72. Through the setting of the transmission structure 7, by rotating the worm 73, the worm gear 72 and the bidirectional screw 71 are driven to rotate, realizing the synchronous adjustment of the first limiting plate 5 and the second limiting plate 13 on both sides to adapt to packaging bags of different widths. The first limiting plate 5 and the second limiting plate 13 are fixedly limited by the self-locking action of the worm gear 72 and the worm 73.

[0023] The buffer structure 16 includes an inner groove 161, a spring 162, a support rod 163, a movable block 164, a connecting rod 165, and a buffer plate 166. The inner groove 161 is located on both sides of the bottom of the machine body 1. The support rod 163 is fixedly connected to the inner groove 161. The spring 162 is sleeved on the surface of the support rod 163. The movable block 164 is slidably connected to the surface of the support rod 163. The two ends of the spring 162 are fixed to the inner groove 161 and the movable block 164, respectively. The connecting rod 165 is hinged to the top of the movable block 164. The buffer plate 166 is hinged to the other end of the connecting rod 165. With the buffer structure 16, when the packaging bag is sealed, it will fall onto the buffer plate 166. The impact force of the packaging bag acts on the buffer plate 166. The connecting rod 165 pushes the movable block 164 to slide along the support rod 163, compressing the spring 162 sleeved on the support rod 163. Through the elastic force of the spring 162 itself, the impact force of the packaging bag falling downward can be reduced.

[0024] A baffle 10 is fixedly connected to the top of the support plate 9. The baffle 10 is rotatably connected to the worm 73. By setting the baffle 10, the worm 73 can be supported when it rotates, and the stability of the worm 73 during rotation can be improved.

[0025] The bottom of the body 1 is provided with a through groove 17, and the through groove 17 is arc-shaped. Because the through groove 17 is arc-shaped, when the buffer plate 166 moves downward by the gravitational potential energy of the packaging bag, the front end of the buffer plate 166 will not squeeze the inner wall of the bottom of the body 1.

[0026] The front end of the worm gear 73 is fixedly connected to a turntable 8, and the turntable 8 has several circular grooves around its perimeter. The turntable 8 allows the operator to manually rotate the worm gear 73 and adjust it.

[0027] Working principle: When the operator seals the packaging bag, the operator first rotates the turntable 8 at the front end of the worm gear 73. The worm gear 73 rotates accordingly, driving the meshing worm wheel 72 to rotate. The worm wheel 72 drives the coaxially fixed bidirectional screw 71 to rotate. The first moving plates 6 on both sides will move synchronously towards or away from each other, and through the connecting plate 15, drive the second moving plate 14 and the second limiting plate 13 behind to move synchronously. By adjusting the distance between the first limiting plate 5 and the second limiting plate 13, it can accommodate bagged condiments of different widths, ensuring that the packaging bag remains centered and does not shift during the conveying process. After adjustment, the self-locking function of the worm gear 73 and the worm wheel 72 prevents the first limiting plate 5 and the second limiting plate 13 from shifting due to vibration or other factors. Then, the bag to be sealed is placed... The packaging bag is placed horizontally between the first roller 4 and the second roller 12, and positioned on both sides by the first limiting plate 5 and the second limiting plate 13. After the machine body 1 is turned on, the first roller 4 and the second roller 12 are driven to rotate by the motor, and the packaging bag is conveyed forward by friction. The first limiting plate 5 and the second limiting plate 13 are always in contact with the sides of the packaging bag to prevent it from swaying or deviating during the conveying process, and to ensure accurate sealing position. After the packaging bag completes the sealing process, it will fall onto the surface of the buffer plate 166. The impact force of the packaging bag acts on the buffer plate 166, and pushes the movable block 164 to slide along the support rod 163 through the connecting rod 165, compressing the spring 162 sleeved on the support rod 163. Through the elastic force of the spring 162 itself, the impact force of the packaging bag falling downward can be reduced.
