Abstract
Description
Technical Field
[0001] This utility model relates to the field of fish bait production and processing technology, specifically to a sealing structure for fish bait packaging bags. Background Technology
[0002] High-quality fish bait, through the scientific formulation of scent components and physical properties, can significantly enhance the fish-attracting effect and the probability of catching fish, thus having a decisive impact on the final catch quantity and the selective fishing of target fish species. In the production process of fish bait, crushing and processing is a crucial step. By finely crushing the raw materials, the particle size, mixing uniformity and solubility of the bait can be optimized, making it present a more natural atomization effect in the water, thereby improving its fish-attracting ability.
[0003] In the packaging stage of fish bait production, problems such as poor sealing of the packaging bags, damage to the bag body, and leakage of filling often occur. These abnormalities can easily lead to insufficient weight of bait inside the packaging bag or even empty bags. However, the existing production equipment will still complete the plastic sealing process according to the established process, which not only reduces the production efficiency of fish bait but also significantly increases the production cost. To address these issues, we propose a sealing structure for fish bait packaging bags. Utility Model Content
[0004] The present invention aims to provide a sealing structure for fish bait packaging bags to solve the problem that existing equipment will still complete the sealing process according to the established procedure even when abnormal situations occur during the sealing process.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sealing structure for a fish bait packaging bag, including a workbench, a sealing assembly on the outer wall of the workbench, a triggering structure on the outer wall of the sealing assembly, the triggering structure including a base, an abutment block, a limiting block, a triggering rod, and a torsion spring, the abutment block being located at one end of the base, a mounting post being located at the end of the abutment block away from the base, a sleeve being located at the end of the mounting post away from the abutment block, the torsion spring being located between the sleeve and the abutment block, the triggering rod being located on the outer wall of the sleeve, the limiting block being located on the outer wall of the sleeve near the abutment block, and the limiting block being able to abut against the abutment block, the outer wall of the abutment block being provided with a triggering button electrically connected to the sealing assembly, and the limiting block being able to abut against the triggering button.
[0006] The beneficial effects of this solution are as follows: The packaging bag filled with fish bait expands in volume, causing it to contact the trigger rod during rotation. This compression forces the trigger rod to rotate, causing the limit block to contact the trigger button, thus allowing the subsequent sealing process to proceed normally. If the expanded packaging bag fails to contact the trigger rod, it indicates that the amount of fish bait inside the bag is insufficient, preventing the limit block from contacting the trigger button and thus avoiding the subsequent sealing process. The torsion spring is used to reset the trigger rod, ensuring proper identification of the packaging bag. The mounting post is used to install the sleeve, and the abutment block limits the rotation range of the limit block. The contact between the expanded packaging bag and the trigger rod causes the trigger rod to drive the limit block to contact the trigger button on the outer wall of the abutment block, thereby detecting whether the amount of fish bait inside the packaging bag is sufficient and determining whether the packaging bag can proceed with the subsequent sealing process, preventing the sealing of packaging bags with insufficient fish bait.
[0007] Preferably, as an improvement, the sealing assembly includes a first support plate and a heat sealing machine. The first support plate is disposed on the outer wall of the worktable, and the heat sealing machine is disposed at the end of the first support plate opposite to the worktable. The heat sealing machine is electrically connected to a trigger button.
[0008] The beneficial effects are as follows: the first support plate is used to install the heat sealing machine, which can seal the opening of the packaging bag.
[0009] Preferably, as an improvement, the outer wall of the worktable is provided with a striking assembly, which includes a second support plate, a mounting base, striking teeth, a guide rail, and a bearing plate. The second support plate is located on the outer wall of the worktable, the mounting base is located at one end of the second support plate opposite to the worktable, a rotating rod is provided inside the mounting base, the striking teeth are located on the outer wall of the rotating rod, a first driving member is provided on the outer wall of the mounting base, and the output end of the first driving member is connected to the rotating rod. The guide rail is located at one end of the second support plate near the worktable, a slider is provided on the outer wall of the guide rail, and a bearing plate is located on the outer wall of the slider. A first cylinder is provided at one end of the second support plate opposite to the worktable, and the output end of the first cylinder is connected to the slider.
[0010] The beneficial effects are as follows: After the bait is filled into the packaging bag, the bait powder gradually adheres to the opening of the packaging bag. As the weight of the packaging bag increases, it will straighten under the action of gravity, causing the openings of the packaging bags to stick together. This further results in the bait powder at the seal being retained there, which is not conducive to the subsequent sealing process. This solution uses a first cylinder to drive the support plate to rise on the outer wall of the guide rail, thereby supporting the packaging bag. During the process of the support plate rising, some air inside the packaging bag can also be expelled, reducing the volume of the packaging bag. At the same time as the air is expelled from the packaging bag, the openings of the packaging bags separate. Then, the first driving component drives the rotating rod to rotate, causing the striking teeth on the outer wall of the rotating rod to rotate. The rotating striking teeth then strike the opening of the packaging bag, knocking off the bait powder adhering to the opening of the packaging bag, thereby ensuring the sealing effect of the packaging bag and improving the use effect of the bait.
[0011] Preferably, as an improvement, a turntable is provided at the upper end of the worktable, and a number of clamping components are provided at one end of the turntable near the worktable. The clamping components include a fixed base and two sets of clamping members. The fixed base is located at one end of the turntable near the worktable, and the two sets of clamping members are symmetrically arranged in the fixed base. The clamping members include a rotating rod, a clamping block, a second cylinder, and a second driving member. The rotating rod is located in the fixed base, the second driving member is located at one end of the fixed base near the worktable, and the output end of the second driving member is connected to the rotating rod. The second cylinder is located in the rotating rod, and the clamping block is located at the output end of the second cylinder, and the clamping block can abut against the rotating rod.
[0012] The beneficial effects are as follows: the two corners of the packaging bag are fixed by two sets of clamping components. During use, the second cylinder drives the clamping block to abut against the end of the rotating rod, thereby fixing the packaging bag. When it is necessary to put fish bait into the packaging bag, the second drive component rotates the two rotating rods, bringing them closer together, thereby squeezing the opening of the packaging bag and opening it. After the packaging bag is filled with fish bait, the turntable drives the clamping component to rotate until it rotates to below the tapping component. The tapping component taps the opening of the packaging bag to ensure that the subsequent plastic sealing is carried out normally.
[0013] Preferably, as an improvement, the outer wall of the workbench is also provided with an extension frame, the upper end of the extension frame is provided with an installation ring, the installation ring is provided with a storage bin, the lower end of the storage bin is provided with a discharge port, and the discharge port is provided with a screw metering scale.
[0014] The beneficial effects are as follows: the heightening frame is used to fix the mounting ring and raise the height of the storage bin, which facilitates the discharge of the storage bin. The discharge port is used to align with the opening of the packaging bag, so that the fish bait is put into the packaging bag. The spiral weighing scale is used to control the weight of the fish bait discharged from the storage bin, ensuring that the weight of each bag of fish bait is consistent.
[0015] Preferably, as an improvement, the first support plate and the second support plate are symmetrically provided with sliding grooves at opposite ends, and an adjustment plate is installed in the sliding grooves. The base is located at the end of the adjustment plate near the worktable.
[0016] The beneficial effect is that by adjusting the position of the adjusting plate in the chute, the contact position between the trigger rod and the packaging bag is changed, thereby enabling the triggering component to adapt to more packaging bags of different specifications.

[0023] Example
[0024] The basic implementation examples are as follows: Figure 1-4 As shown, Figure 1The diagram illustrates a sealing structure for a fish bait packaging bag, comprising a workbench 1. A collection slot 22 is annularly formed at the upper end of the workbench 1, used to collect spilled fish bait for easy cleaning by staff.

The fixed base 12 is fixedly installed at the lower end of the turntable 11. The two sets of clamping members are symmetrically rotatably installed within the fixed base 12. Each clamping member includes a rotating rod 13, a clamping block 14, a second cylinder 15, and a second driving member 16. The rotating rod 13 is rotatably installed within the fixed base 12. The second driving member 16 is fixedly installed at the lower end of the fixed base 12, and its output end is fixedly connected to the rotating rod 13 within the fixed base 12. The second cylinder 15 is fixedly installed inside the rotating rod 13, with its output end extending through the rotating rod 13. A clamping block 14 is fixedly installed at the output end of the second cylinder 15 and can abut against the end of the rotating rod 13. The second cylinder 15 controls the clamping block 14 to tighten or loosen against the end of the rotating rod 13, thereby clamping and loosening the packaged bag. A tapping assembly is fixedly installed on the outer wall of the worktable 1. Figure 3 The shown striking assembly includes a second support plate 2, a mounting base 3, striking teeth 4, a guide rail 5, and a bearing plate 6, as shown. Figure 1 The second support plate 2 shown is fixedly installed on the outer wall of the workbench 1, as shown. Figure 3 The mounting base 3 shown is fixedly installed at the lower end of the second support plate 2. A rotating rod 7 is rotatably installed inside the mounting base 3. The striking teeth 4 are fixedly installed on the outer wall of the rotating rod 7. A first driving component 8 is fixedly installed at the right end of the mounting base 3, and the output end of the first driving component 8 is fixedly connected to the rotating rod 7. A guide rail 5 is fixedly installed at the front end of the second support plate 2. A slider 9 is slidably installed on the outer wall of the guide rail 5. A bearing plate 6 is fixedly installed at the front end of the slider 9. A first cylinder 10 is fixedly installed at the lower end of the second support plate 2, and the output end of the first cylinder 10 is fixedly connected to the upper end of the slider 9. Both the first driving component 8 and the second driving component 16 are set as servo motors.
[0025] like Figure 1 The first support plate 23 and the second support plate 2 shown are symmetrically provided with sliding grooves 34 at opposite ends. An adjusting plate 25 is slidably installed within the sliding grooves 34. The outer walls of the first support plate 23 and the second support plate 2 have several threaded holes communicating with the sliding grooves 34. Each threaded hole is threaded with a bolt, and the adjusting plate 25 within the sliding groove 34 is fixed by tightening the bolts. A triggering structure is located at the end of the adjusting plate 25 near the worktable 1. Figure 4 The triggering structure shown includes a base 26, an abutment block 27, a limiting block 28, a trigger rod 29, and a torsion spring 30. The abutment block 27 is fixedly installed on the upper end of the base 26. The abutment block 27 is a rectangular column. A mounting post 31 is fixedly installed on the upper end of the abutment block 27. A sleeve 32 is rotatably installed on the upper end of the mounting post 31. The two ends of the torsion spring 30 are respectively fixedly installed between the sleeve 32 and the abutment block 27. The trigger rod 29 is fixedly installed on the outer wall of the sleeve 32. The limiting block 28 is fixed. Installed on the lower outer wall of the sleeve 32, the limiting block 28 can abut against the abutting block 27. The limiting block 28 is set in an "L" shape and includes a long side and a short side. The long side of the limiting block 28 abuts against the outer wall of the abutting block 27. The sleeve 32 can only rotate along the short side of the limiting block 28, thereby limiting the rotation angle of the sleeve 32. The outer wall of the abutting block 27 is provided with a trigger button 33 that is electrically connected to the sealing assembly, and the short side of the limiting block 28 can abut against the trigger button 33.
[0026] The specific implementation process is as follows:
[0027] In use, the operator first places the packaging bag between the rotating rod 13 and the clamping block 14. Then, by controlling the second cylinder 15, the clamping block 14 is driven to abut against the end of the rotating rod 13, thereby fixing the packaging bag. Subsequently, the turntable 11 drives the clamping assembly to rotate directly below the storage bin 19. At this time, the two second drive members 16 of the clamping assembly rotate the rotating rod 13 connected to them respectively, bringing the two rotating rods 13 closer together, thereby squeezing open the opening of the packaging bag. Then, fish bait is put into the packaging bag through the screw weighing scale 21. After the packaging bag is filled, the two second drive members 16 rotate the rotating rod 14 connected to them again. 3. The two rotating rods 13 are moved away from each other, thus tightening the opening of the packaging bag and making the openings of the packaging bags fit together, facilitating subsequent sealing. Then, the turntable 11 drives the clamping assembly to rotate below the striking assembly. At this time, the first cylinder 10 controls the slider 9 to slide upward, thereby lifting the packaging bag through the support plate 6, allowing some of the air inside the packaging bag to be expelled, thus separating the openings of the packaging bags. At the same time, the first driving component 8 drives the rotating rod 7 to rotate, causing the striking teeth 4 to strike the opening of the packaging bag, knocking off the bait powder adhering to the opening of the packaging bag, thereby ensuring the sealing effect of the packaging bag and improving the use effect of the fish bait.
[0028] After being tapped, the packaged bag rotates to the bottom of the first support plate 23 under the action of the turntable 11. During the rotation of the packaged bag, it passes through the triggering structure. If the amount of fish bait in the packaged bag is up to standard, it will contact the trigger rod 29, causing the trigger rod 29 to drive the sleeve 32 to rotate. This causes the limit block 28 to contact the trigger button 33, which in turn controls the heat sealing machine 24 to work and seal the opening of the packaged bag. If the amount of fish bait in some packaged bags is not up to standard, it will not contact the trigger rod 29 or will not be enough to cause the limit block 28 to abut against the trigger button 33. This causes the heat sealing machine 24 to stop working and not seal the packaged bags with insufficient fish bait, thereby reducing the production cost of fish bait.
