Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to a leak-proof sealing strip for vermicelli packaging. Background Technology

[0002] Vermicelli packaging refers to containers used to hold vermicelli. These containers are made of plastic, paper, or composite film and feature airtightness, easy loading and unloading, and fixed volume and quantity. They are available in bag and box forms, and some containers have moisture-proof and light-proof functions. The opening is designed with a self-sealing strip or tear-off seal to prevent the vermicelli from getting damp and maintain its texture. They are used in food storage and supermarket sales scenarios, providing convenience for the preservation and sale of vermicelli.

[0003] Air-proof sealing strips for vermicelli packaging are designed to solve the problem of air leakage during the storage and transportation of vermicelli. If the packaging is not properly sealed, outside air can enter, causing the vermicelli to become damp and soft, affecting its taste and quality. It can also breed bacteria and shorten its shelf life. Air-proof sealing strips form a sealing barrier by tightly fitting the strip to the edge of the packaging seal. The pressure of the strip itself strengthens the sealing effect, effectively preventing air from entering and internal gas from escaping, keeping the vermicelli dry and fresh, and improving the safety and quality stability of vermicelli storage.

[0004] When sealing vermicelli, the airtight sealing strip relies solely on the stress generated by its own deformation to compress the packaging. While this can reduce air entry to some extent, the sealing performance is limited. Outside air can seep in, causing the vermicelli to become damp and deteriorate, affecting its quality and shelf life. In actual use, when the packaging is subjected to compression, impact, or temperature changes, the stress on the sealing strip weakens due to force fluctuations or material fatigue, resulting in gaps at the seal and compromising the packaging's airtightness. This makes it difficult to guarantee the vermicelli's storage airtightness and stability. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides: a leak-proof sealing strip for vermicelli packaging, including a strip body 1, a clamping mechanism 3 at the bottom of the strip body 1 for clamping and sealing the packaging, a packaging bag 2 at the bottom of the strip body 1, a locking mechanism 4 at the top left of the packaging bag 2 for fixing the strip after the packaging is sealed, a sealing mechanism 5 at the top of the packaging bag 2, and a gripping mechanism 6 at the top of the strip body 1;

[0035] The clamping mechanism 3 includes two clamping strips 31. The tops of the two clamping strips 31 are fixedly connected to the front and rear sides of the bottom of the pressure strip body 1, respectively. Multiple mounting blocks 32 are fixedly connected to the opposite sides of the two clamping strips 31. Rotating shafts 33 are rotatably connected to the adjacent sides of the multiple mounting blocks 32. Irregularly shaped columns 34 are rotatably connected between the adjacent sides of the multiple rotating shafts 33. Pressing blocks 35 are fixedly connected to the top of the outer walls of the multiple irregularly shaped columns 34. Positioning components 36 are provided on the left and right sides of the multiple irregularly shaped columns 34. Sealing strips 37 are fixedly connected to the top of the adjacent sides of the two clamping strips 31. Limiting slides 38 are fixedly connected to the bottom of the adjacent sides of the two clamping strips 31.

[0036] Specifically, the gripping mechanism 6 picks up the pressure strip body 1, the sealing mechanism 5 on the packaging bag 2 is placed between the two clamping strips 31, and the clamping strips 31 are slid in laterally. Then, multiple pressing blocks 35 are pressed. Since the pressing blocks 35 are fixedly connected to the top of the outer wall of the irregular column 34, and the irregular column 34 is rotatably connected between adjacent rotating shafts 33, and the rotating shafts 33 are rotatably connected to the adjacent side of the mounting block 32, and the mounting block 32 is fixedly connected to the side of the clamping strips 31 that is far away, the pressing blocks 35 will drive the irregular column 34 to rotate around the rotating shaft 33 after being pressed.

[0037] During the rotation of the irregular column 34, the positioning components 36 on the left and right sides of the irregular column 34 will limit the rotation angle of the irregular column 34 to ensure that the irregular column 34 can rotate stably towards the clamping strip 31. As the irregular column 34 rotates, it will exert a squeezing force on the sealing mechanism 5 between the two clamping strips 31, causing the sealing mechanism 5 to tighten and close.

[0038] Each of the two clamping strips 31 has a sealing strip 37 fixedly connected to the top of its adjacent side. As the clamping strips 31 come together, the sealing strip 37 will first come into contact with the sealing mechanism 5 on the packaging bag 2 and gradually adhere to it, thus initially achieving a sealing effect. At the same time, the limiting slide strip 38 fixedly connected to the bottom of the two clamping strips 31 will slide along the sealing mechanism 5, which will guide and limit the movement of the clamping strips 31, prevent the clamping strips 31 from shifting during the coming together process, and ensure the sealing performance.

[0039] When the pressing block 35 is stopped, the positioning component 36 will fix the position of the irregular column 34, thereby keeping the sealing mechanism 5 in a clamped state. At this time, the sealing strip 37 is tightly attached to the sealing mechanism 5 to achieve a good sealing effect and prevent air leakage.

[0040] After sealing, the pressure strip body 1 is fixed by the locking mechanism 4 on the top left side of the packaging bag 2 to further ensure the stability of the seal, while the gripping mechanism 6 makes it convenient for users to pick up and move the pressure strip body 1 during operation, improving the ease of operation.

[0041] Reference Figure 2 and Figure 5 The locking mechanism 4 includes a lock body 41, the bottom of which is fixedly connected to the top left side of the packaging bag 2. A lock tongue 42 passes through the inside of the lock body 41. A lock hole 43 is opened on the left side of the pressure strip body 1. A spring 44 is fixedly connected to the bottom of the inner side of the lock body 41. The top of the spring 44 is fixedly connected to the bottom of the lock tongue 42. A cap 45 is fixedly connected to the top of the lock tongue 42.

[0042] Specifically, align the left side of the pressure strip body 1 with the lock body 41. At this time, the latch 42 is in a naturally extended state under the action of the second spring 44. As the pressure strip body 1 moves closer to the lock body 41, the left edge of the pressure strip body 1 will contact the end of the latch 42. Continue to push the pressure strip body 1. The latch 42 is squeezed by the pressure strip body 1 and will overcome the elastic force of the second spring 44 and move downward. The second spring 44 is compressed accordingly. When the lock hole 43 on the pressure strip body 1 moves to the position corresponding to the latch 42, the squeezing force on the latch 42 disappears. Under the action of the elastic restoring force of the second spring 44, the latch 42 moves upward and passes through the lock hole 43. At this time, the top of the latch 42 abuts against the inside of the lock hole 43, realizing the locking of the pressure strip body 1 and the packaging bag 2. The post cap 45 is fixedly connected to the top of the latch 42, which can provide a force point for subsequent unlocking operations.

[0043] Press down on the cap 45. The cap 45 drives the bolt 42 to move downward in sync. The second spring 44 is compressed. As the bolt 42 moves downward, it gradually exits from the keyhole 43. When the bolt 42 is completely disengaged from the keyhole 43, the constraint between the pressure bar body 1 and the lock body 41 is released. At this time, the pressure bar body 1 can be separated from the packaging bag 2 to complete the unlocking operation. Release the pressure on the cap 45. The bolt 42 moves upward again under the elastic thrust of the second spring 44 and returns to its initial extended state so that the next locking operation can be performed.

[0044] Throughout the entire operation, spring 44 always provides an upward elastic force to the latch 42, ensuring that the latch 42 can be stably kept in the lock hole 43 when there is no external force pressing, thus ensuring the reliability of the locked state. By applying a downward external force to the cap 45, the movement of the latch 42 can be easily controlled to achieve quick unlocking, making the locking mechanism 4 easy to operate and securely locked.

[0045] Reference Figure 2 , Figure 3 and Figure 4The sealing mechanism 5 includes a sealing strip 51, the bottom of which is fixedly connected to the top of the packaging bag 2. An opening 52 is provided at the top of the sealing strip 51. Sealing strips 53 are fixedly connected to the top of the opposite sides of the sealing strip 51. A docking assembly 54 is provided on the right side of the pressure strip body 1. A damping assembly 55 is provided on the opposite sides of the sealing strip 51. A limit groove 56 is provided at the bottom of the opposite sides of the sealing strip 51. The gripping mechanism 6 includes a mounting block 61, the bottom of which is fixedly connected to the top of the pressure strip body 1. The front and rear sides of the mounting block 61 are fixedly connected to the top of the pressure strip body 1. Multiple anti-slip particles 62 are connected, and multiple anti-slip strips 63 are fixedly connected to the front and rear sides of the mounting block 61. The positioning component 36 includes multiple springs 362. The adjacent sides of the multiple springs 362 are fixedly connected to the left and right sides of the multiple irregular columns 34. The left and right sides of the multiple irregular columns 34 are provided with grooves 361. The adjacent sides of the multiple springs 362 are fixedly connected to the inner walls of the multiple grooves 361. The opposite sides of the multiple springs 362 are fixedly connected with small balls 363. The adjacent sides of the multiple mounting blocks 32 are provided with grooves 364.

[0046] Specifically, the sealing strip 51 provides a sealing structure support for the packaging bag 2 and allows the pressure strip body 1 to be installed on the top of the packaging bag 2. The sealing strip 53 fits tightly during the closing process of the opening 52 to ensure the sealing performance. The docking component 54 on the right side of the pressure strip body 1 enables the sealing strip 51 to be accurately docked and positioned during the sealing process. At the same time, the damping component 55 on the side away from the sealing strip 51 can provide appropriate resistance and friction to prevent the sealing strip 51 from affecting the sealing effect due to excessive movement during operation, and to reduce the offset phenomenon that occurs after the pressure strip body 1 completes the sealing of the packaging bag 2. The limiting slide groove 56 is slidably connected to the limiting slide strip 38 to realize the limiting effect of the sealing mechanism 5 on the movement of the clamping mechanism 3, ensuring that the clamping mechanism 3 moves within the set trajectory.

[0047] The bottom of mounting block 3 61 is fixedly connected to the top of the pressure strip body 1. The operator can pick up and move the pressure strip body 1 by holding the mounting block 3 61. Multiple anti-slip particles 2 62 and multiple anti-slip strips 2 63 on the front and back sides of the mounting block 3 61 increase the friction between the hand and the mounting block 3 61, effectively preventing slippage during the operation of the pressure strip body 1 and ensuring that the operator can apply force stably.

[0048] When the irregular column 34 rotates around the horizontal axis along the rotating shaft 33 within the mounting block 32, the ball 363 leaves the groove 364. At this time, the spring 362 is compressed by the ball 363 and compresses inward. The irregular column 34 can then rotate freely. The irregular column 34 continues to rotate downward until it completes the compression and clamping of the sealing strip 51. The ball 363 re-enters the groove 364, and the spring 362 returns to its natural extended state. Under the elastic force of the spring 362, the ball 363 is inserted into the groove 364, thereby achieving the positioning of the rotation angle of the irregular column 34 within the mounting block 32.

[0049] Reference Figure 1 , Figure 2 and Figure 6 The docking component 54 includes a second mounting block 541, the left side of which is fixedly connected to the right side of the pressure strip body 1. A pin 542 is fixedly connected to the right side of the inner wall of the second mounting block 541. An insertion port 543 is opened at the top right side of the packaging bag 2. The inner wall of the insertion port 543 is slidably connected to the outer wall of the pin 542. The damping component 55 includes multiple anti-slip particles 551. The adjacent sides of the multiple anti-slip particles 551 are fixedly connected to the front and rear sides of the sealing strip 51. Multiple anti-slip strips 552 are fixedly connected to the front and rear sides of the sealing strip 51. A base 7 is fixedly connected to the right side of the packaging bag 2. A lifting ring 8 is fixedly connected to the right side of the base 7.

[0050] Specifically, after the sealing strip body 1 completes the sealing work of the packaging bag 2, the pin 542 on the right side of the inner wall of the mounting block 2 541 forms a sliding connection with the insertion port 543 opened on the top right side of the packaging bag 2 and is inserted into the insertion port 543. Through the tight engagement of the pin 542 and the insertion port 543, the sealing strip body 1 and the packaging bag 2 are further fixed, preventing the sealing strip body 1 from flipping under the action of external torque, and providing further support for the sealing function of the clamping mechanism 3 and the sealing mechanism 5.

[0051] The damping component 55 includes multiple anti-slip particles 551, which are fixedly connected to the front and rear sides of the sealing tape 51. When the sealing tape 51 contacts the packaging bag 2, the multiple anti-slip particles 551 in the damping component 55 generate frictional resistance with the inner wall of the packaging bag 2, effectively preventing the sealing tape 51 from sliding relative to the packaging bag 2 during use. The multiple anti-slip strips 552 on the sealing tape 51 form a secondary anti-slip with the contact surface of the packaging bag 2. By increasing the friction coefficient of the contact surface, the tightness of the seal between the sealing tape 51 and the packaging bag 2 is further improved, ensuring the sealing at the seal and preventing leakage of the contents inside the packaging bag 2.

[0052] Users can lift the base 7 by pulling the lifting ring 8, and then lift the entire packaging bag 2 and the pressure strip body 1 through the fixed connection between the base 7 and the packaging bag 2. At this time, the tension on the lifting ring 8 is evenly transmitted to the packaging bag 2 through the base 7, which ensures the structural stability of the packaging bag 2 during carrying and avoids damage to the packaging bag 2 due to excessive local stress.

[0053] Working principle: The pressure strip body 1 is picked up by the gripping mechanism 6. The multiple anti-slip particles 2 62 and anti-slip strips 2 63 on the front and rear sides of the installation block 3 61 can increase the friction between the hand and the installation block 3 61, effectively preventing slippage during operation, ensuring that the operator can stably pick up and move the pressure strip body 1, and improving the ease of operation.

[0054] When the sealing mechanism 5 on the packaging bag 2 is placed between the two clamping strips 31 and slid laterally into the clamping strips 31, and then multiple pressing blocks 35 are pressed down, the pressure on the pressing blocks 35 is transmitted to the irregular column 34, causing the irregular column 34 to rotate around the rotating shaft 33. During the rotation of the irregular column 34, the positioning components 36 on its left and right sides limit the rotation angle. When the irregular column 34 rotates around the horizontal axis of the rotating shaft 33, the small ball 363 will disengage from the groove 364. At this time, the spring 362 is compressed inward by the pressure of the small ball 363, causing the irregular column to... The shaped column 34 can rotate freely. When the shaped column 34 rotates to move towards the clamping strip 31 and completes the squeezing and clamping of the sealing mechanism 5, the ball 363 will re-enter the groove 364, and the spring 362 will return to its natural extended state. Under the action of elastic force, the ball 363 will be stuck in the groove 364, thereby limiting the rotation angle of the shaped column 34 and ensuring that it rotates stably towards the clamping strip 31. As the shaped column 34 rotates, it will generate a squeezing force on the sealing mechanism 5 between the two clamping strips 31, causing the sealing mechanism 5 to tighten and close.

[0055] A sealing strip 37 is fixedly connected to the top of each adjacent side of the two clamping strips 31. During the process of the clamping strips 31 approaching each other, the sealing strip 37 will first contact the sealing mechanism 5 on the packaging bag 2 and gradually adhere to it, thus initially achieving a sealing effect. At the same time, the limiting slide strip 38 fixedly connected to the bottom of each adjacent side of the two clamping strips 31 will slide along the sealing mechanism 5. The limiting slide strip 38 can guide and limit the movement of the clamping strips 31, preventing the clamping strips 31 from shifting during the approaching process and ensuring the accuracy of the sealing action.

[0056] When the pressing block 35 is stopped, the positioning component 36 will fix the position of the irregular column 34, and the ball 363 will be stably inserted into the groove 364, so that the irregular column 34 maintains the squeezing force on the clamping strip 31, thereby keeping the sealing mechanism 5 in a clamped state. At this time, the sealing strip 37 is tightly attached to the sealing mechanism 5 to achieve a good sealing effect and prevent gas leakage inside the packaging bag 2.

[0057] After the sealing mechanism 5 is clamped, the pressure strip body 1 needs to be fixed by the locking mechanism 4 on the top left side of the packaging bag 2 to further ensure the sealing stability. Align the left side of the pressure strip body 1 with the position of the lock body 41. At this time, the locking tongue 42 inside the lock body 41 is in a naturally extended state under the action of the second spring 44. As the pressure strip body 1 moves closer to the lock body 41, the left edge of the pressure strip body 1 will contact the end of the locking tongue 42. Continue to push the pressure strip body 1. The locking tongue 42 is squeezed by the pressure strip body 1 and will overcome the elastic force of the second spring 44 and move downward. The second spring 44 will be compressed accordingly. When the lock hole 43 on the pressure strip body 1 moves to the position corresponding to the locking tongue 42, the squeezing force on the locking tongue 42 disappears. Under the action of the elastic restoring force of the second spring 44, the locking tongue 42 moves upward and passes through the lock hole 43. The top of the locking tongue 42 abuts against the inside of the lock hole 43, realizing the locking of the pressure strip body 1 and the packaging bag 2. In addition, the post cap 45 fixedly connected to the top of the latch 42 provides a force point for subsequent unlocking. When unlocking, press the post cap 45 down to drive the latch 42 to move down synchronously. The second spring 44 is compressed. When the latch 42 is completely disengaged from the lock hole 43, the constraint between the pressure bar body 1 and the lock body 41 is released, and the pressure bar body 1 can be separated from the packaging bag 2. After releasing the press, the latch 42 moves up again under the elastic thrust of the second spring 44, restoring the initial extended state for the next locking operation.

[0058] The sealing strip 51 of the sealing mechanism 5 provides a sealing connection support for the packaging bag 2, allowing the pressure strip body 1 to be installed on the top of the packaging bag 2. The sealing strip 37, which is fixedly connected to the top of the two adjacent clamping strips 31, will first contact the sealing mechanism 5 and gradually fit together during the process of the clamping strips 31 approaching, thus initially achieving a sealing effect. The limiting slide strip 38, which is fixedly connected to the bottom of the two adjacent clamping strips 31, will slide along the sealing mechanism 5, guiding and limiting the movement of the clamping strips 31, preventing the clamping strips 31 from shifting during the approaching process, and ensuring the sealing performance. The damping components 55 on the front and rear sides of the sealing tape 51 enhance stability through a dual anti-slip mechanism. When the sealing tape 51 comes into contact with the packaging bag 2, the multiple anti-slip particles 551 on the damping components 55 generate frictional resistance with the inner wall of the packaging bag 2, preventing the sealing tape 51 from sliding relative to the packaging bag 2. The multiple anti-slip strips 552 on the sealing tape 51 form a secondary anti-slip with the contact surface of the packaging bag 2. By increasing the friction coefficient of the contact surface, the tightness of the connection between the sealing tape 51 and the packaging bag 2 is further improved, ensuring the sealing at the seal and preventing leakage of the contents inside the packaging bag 2.

[0059] After the sealing strip body 1 completes the sealing work of the packaging bag 2, the pin 542 on the right side of the inner wall of the second mounting block 541 will form a sliding connection with the insertion port 543 opened on the top right side of the packaging bag 2 and be inserted into the insertion port 543. Through the tight engagement of the pin 542 and the insertion port 543, the sealing strip body 1 and the packaging bag 2 are further fixed, preventing the sealing strip body 1 from flipping due to the action of external torque, and providing more reliable support for the sealing function of the clamping mechanism 3 and the sealing mechanism 5.

[0060] When the pressing block 35 is stopped, the positioning component 36 fixes the position of the irregular column 34, keeping the sealing mechanism 5 in a clamped state. The sealing strip 37 fits tightly against the sealing mechanism 5. Combined with the tight fit of the sealing strip 53 during the closing process of the opening 52, a good sealing effect is achieved to prevent air leakage. The sliding connection between the limiting slide strip 38 and the sealing mechanism 5 will ensure that the clamping strip 31 does not shift during the whole process, further ensuring the sealing performance.

[0061] By pulling the lifting ring 8 to move the base 7, since the base 7 is fixedly connected to the packaging bag 2, the pulling force on the lifting ring 8 will be evenly transmitted to the packaging bag 2 through the base 7, ensuring the structural stability of the packaging bag 2 during carrying and avoiding damage to the packaging bag 2 due to excessive local stress.
