Description

Technical Field

[0001] This utility model belongs to the technical field of cable tie packaging equipment, specifically relating to a packaging bag sealing mechanism for a cable tie packaging machine. Background Technology

[0002] Cable ties, also known as wire ties, cable bundles, or locking straps, are strip-shaped tools used for bundling items. Depending on the material, they can be divided into nylon cable ties, stainless steel cable ties, and powder-coated stainless steel cable ties, etc.; according to function, they include ordinary cable ties, removable cable ties, label cable ties, fixed locking cable ties, pin-type cable ties, and heavy-duty cable ties, among others. Cable ties have advantages such as acid resistance, corrosion resistance, good insulation, aging resistance, lightweight, safety and non-toxicity, and high load-bearing capacity, and are widely used in bundling operations for electromechanical products, cables, computers, electronic products, automotive wiring harnesses, and other fields.

[0003] Cable ties are typically manufactured using injection molding. The finished product generally consists of a base plate with a row of cable ties formed along both edges. These ties are then separated using a shearing device and placed into packaging bags. Finally, the bags are transferred to a sealing machine for sealing, completing the packaging process. However, currently, most sealing operations still rely on manual loading and unloading, which significantly hinders improvements in production efficiency. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] During operation, the transfer mechanism returns to its initial position, placing the first gripping mechanism at the bag-picking station, the second gripping mechanism at the bag-filling station, and the third gripping mechanism at the sealing station. After the bag-filling and sealing mechanisms each complete one processing cycle, the first gripping mechanism picks up a packaging bag, the second gripping mechanism picks up a bag already secured with cable ties at the bag-filling station, and the third gripping mechanism picks up a sealed bag at the sealing station.

The pressing mechanism is activated, and the symmetrically arranged third cylinders extend simultaneously, with two second pressure plates cooperating to press the bag opening to achieve a seal. The vacuum machine is activated, and air is extracted from the packaging bag through the tube. After vacuuming is completed, the tube-inserting mechanism pulls out the tube.

The heating element fuses the bag opening through heat sealing, quickly completing the sealing operation and improving production efficiency.

[0038] With the above technical solution, during operation, the transfer mechanism 5 returns to its initial position. The first gripping mechanism 19 of the transfer mechanism 5 is located at the bag picking station, the second gripping mechanism 20 is located at the bag filling mechanism 3 station, and the third gripping mechanism 21 is located at the sealing mechanism 4 station. After the bag filling mechanism 3 and the sealing mechanism 4 have completed one processing, the first gripping mechanism 19 grips and fixes a packaging bag, the second gripping mechanism 20 grips and fixes the packaging bag with the tie attached at the bag filling mechanism 3 station, and the third gripping mechanism 21 grips and fixes the sealed packaging bag at the sealing mechanism 4 station. The fourth cylinder 17 of the transfer mechanism 5 drives the transfer table 18 to move, which in turn drives the first gripping mechanism 19, the second gripping mechanism 20, and the third gripping mechanism 21 to transfer the workstation. At this time, the first gripping mechanism 19 moves the packaging bag to the bagging mechanism 3 workstation and continues to load the cable ties. The second gripping mechanism 20 moves the packaged bag with the cable ties to the sealing mechanism 4 workstation and continues to seal the packaged bag. The third gripping mechanism 21 moves the sealed packaged bag to the unloading workstation. Through continuous operation, the packaging bags are transferred to different processing workstations simultaneously, thereby improving production efficiency.

[0039] The sealing mechanism 4 of this utility model includes a heat-sealing mechanism 7, a pressing mechanism 8, a first bag-clamping mechanism 9, and a tube-inserting mechanism 10. During operation, the packaging bag is transferred to the sealing mechanism 4, the first bag-clamping mechanism 9 clamps and fixes the packaging bag, the tube-inserting mechanism 10 inserts the tube 51 into the packaging bag, the tube 51 is connected to the vacuum machine, the pressing mechanism 8 is activated, the symmetrically arranged third cylinders 15 extend simultaneously, and the two second pressure plates 16 cooperate to press the bag opening of the packaging bag to seal the packaging bag. The vacuum machine is activated, and the air in the packaging bag is extracted through the tube 51. After the vacuum is completed, the tube-inserting mechanism 10 pulls the tube 51 out of the packaging bag. The first cylinder 11 and the second cylinder 12 of the heat-sealing mechanism 7 are activated, so that the heating component 13 and the first pressure plate 14 cooperate to press the bag opening. The heating component 13 welds the bag opening by heat-sealing, quickly completing the sealing operation and improving production efficiency.

[0040] The first gripping mechanism 19, the second gripping mechanism 20, and the third gripping mechanism 21 of this utility model are all the same mechanism. When the gripping command is executed, the symmetrically arranged fifth cylinder 22 extends at the same time, and the two top blocks 23 cooperate to clamp the packaging bag. The gripping mechanism is simple in structure and stable in operation, reducing manufacturing costs.

[0041] Example 2:

[0042] In this embodiment, the frame 2 is fixedly mounted with a bagging mechanism 3, a sealing mechanism 4, and a transfer mechanism 5. The sealing mechanism 4 includes a fixing frame 6, on which a heat-sealing mechanism 7, a pressing mechanism 8, a first bag clamping mechanism 9, and a tube insertion mechanism 10 are fixedly mounted. The heat-sealing mechanism 7 includes a first cylinder 11 and a second cylinder 12. A heating element 13 is fixedly mounted on the driving end of the first cylinder 11, and a first pressure plate 14 is fixedly mounted on the driving end of the second cylinder 12. The pressing mechanism 8 includes symmetrically arranged third cylinders 15, on which a second pressure plate 16 is fixedly mounted. The transfer mechanism 5 includes a fourth cylinder 17, on which a transfer table 18 is fixedly mounted. The transfer table 18 is fixedly mounted with a first gripping mechanism 19, a second gripping mechanism 20, and a third gripping mechanism 21. The first gripping mechanism 19, the second gripping mechanism 20, and the third gripping mechanism 21 are all the same mechanism, each including a symmetrically arranged fifth cylinder 22. The drive end of the fifth cylinder 22 is fixedly mounted with a top block 23, and the top block 23 is equipped with a buffer rubber block to prevent damage to the packaging bag.

[0043] During operation, the transfer mechanism 5 first returns to its initial position, positioning the first gripping mechanism 19 at the bag-picking station, the second gripping mechanism 20 at the bagging mechanism 3 station, and the third gripping mechanism 21 at the sealing mechanism 4 station. After the bagging mechanism 3 and sealing mechanism 4 each complete one processing cycle, the first gripping mechanism 19 picks up an unprocessed packaging bag, the second gripping mechanism 20 picks up a packaging bag with cable ties already attached at the bagging mechanism 3 station, and the third gripping mechanism 21 picks up a sealed packaging bag at the sealing mechanism 4 station. Subsequently, the fourth cylinder 17 of the transfer mechanism 5 drives the transfer table 18 to move, causing the first gripping mechanism 19, the second gripping mechanism 20, and the third gripping mechanism 21 to simultaneously transfer to different stations. The first gripping mechanism 19 moves the packaging bag to the bagging mechanism 3 station to continue adding cable ties, the second gripping mechanism 20 moves the packaged bag with cable ties to the sealing mechanism 4 station to continue sealing, and the third gripping mechanism 21 moves the sealed packaging bag to the unloading station. This continuous operation method enables the synchronous transfer of packaging bags to different processing stations, thereby improving production efficiency.

[0044] In the working process of the sealing mechanism 4, after the packaging bag is transferred to the sealing mechanism 4, the first bag clamping mechanism 9 clamps and fixes the packaging bag, and the tube insertion mechanism 10 inserts the tube 51 into the packaging bag. The tube 51 is connected to the vacuum machine. The pressing mechanism 8 is activated, and the symmetrically arranged third cylinders 15 extend simultaneously. The two second pressure plates 16 cooperate to press the opening of the packaging bag to achieve a seal. The vacuum machine is activated, and the air inside the packaging bag is extracted through the tube 51. After the vacuum is completed, the tube insertion mechanism 10 pulls out the tube 51. The first cylinder 11 and the second cylinder 12 of the heat-sealing mechanism 7 are activated, so that the heating element 13 and the first pressure plate 14 cooperate to press the bag opening. The heating element 13 welds the bag opening by heat sealing, quickly completing the sealing operation and further improving production efficiency.

[0045] When the first gripping mechanism 19, the second gripping mechanism 20, and the third gripping mechanism 21 execute the gripping command, the symmetrically arranged fifth cylinder 22 extends simultaneously, and the two top blocks 23 cooperate to clamp the packaging bag. The gripping mechanism has a simple structure and stable operation, which helps to reduce manufacturing costs. The entire embodiment achieves automatic transfer and sealing of packaging bags by coordinating the actions of each mechanism, reducing manual intervention and improving overall production smoothness and efficiency.

[0046] Example 3:

[0047] The bagging mechanism 3 of this embodiment includes a bag-pulling mechanism 24, a flaring mechanism 25, and a second bag-clamping mechanism 26. The bag-pulling mechanism 24 is equipped with symmetrically arranged sixth cylinders 27, each with a suction nozzle 28 fixedly mounted at its drive end. The flaring mechanism 25 includes a first lifting mechanism 29, which consists of a lifting cylinder 30 and a lifting plate 31. A first guide rail 32 is fixedly mounted on the lifting plate 31. The first guide rail 32 is movably connected to a first moving plate 33 and a second moving plate 34 via a slider, and both moving plates are fixedly mounted with a lever 35. A seventh cylinder 36 is fixedly mounted on the first moving plate 33, and its drive end is fixedly connected to the second moving plate 34. The second bag-clamping mechanism 26 is used to clamp and fix the packaging bag.

[0048] After the transfer mechanism 5 delivers the packaging bag to the bagging mechanism 3, the second bag clamping mechanism 26 activates to clamp the packaging bag for stability. The bag pulling mechanism 24 starts, and the symmetrically arranged sixth cylinder 27 extends, driving the suction nozzle 28 to move to both sides of the packaging bag and suction the bag body. Subsequently, the sixth cylinder 27 retracts, driving the suction nozzle 28 to pull open the bag opening, forming a preliminary opening. The flaring mechanism 25 then operates, and the lifting cylinder 30 of the first lifting mechanism 29 drives the lifting plate 31 to descend, causing the lever 35 to insert into the opened bag opening. The seventh cylinder 36 extends, pushing the first moving plate 33 and the second moving plate 34 to move relatively away from each other along the first guide rail 32, driving the two levers 35 to expand outward, thereby further widening the bag opening. This process ensures that the bag opening is fully opened, facilitating the smooth entry of the tie into the packaging bag, realizing automated bagging operation.

[0049] This embodiment effectively solves the problem of low efficiency in manual operation by coordinating the bag-pulling mechanism 24 and the widening mechanism 25. The bag-pulling mechanism 24 uses a cylinder and a suction nozzle 28 to initially open the bag opening, while the widening mechanism 25 expands the bag opening to the appropriate size through a lifting and lateral movement mechanism. The entire process is continuous and requires no manual intervention, significantly improving the production efficiency and automation level of cable tie packaging. The mechanism is rationally designed with a clear sequence of actions, ensuring the stability and reliability of the packaging bag during the bagging process.

[0050] Example 4:

[0051] In this embodiment, the first bag clamping mechanism 9 and the second bag clamping mechanism 26 adopt the same structural design, both including an eighth cylinder 37 as the main driving component. The driving end of the eighth cylinder 37 is fixedly connected to the third moving plate 38. When the eighth cylinder 37 is activated, it can push the third moving plate 38 to move in a predetermined direction, thereby adjusting the overall position of the bag clamping mechanism to meet the bag clamping requirements. A second guide rail 39 and a first motor 40 are installed on the third moving plate 38. The second guide rail 39 is movably connected to the fourth moving plate 64 through a slider, allowing the fourth moving plate 64 to slide smoothly along the guide rail. The driving end of the first motor 40 is fixedly connected to the first lead screw 41. The first lead screw 41 cooperates with the lead screw nut installed on the third moving plate 38. When the first motor 40 is running, it drives the fourth moving plate 64 to move relative to the third moving plate 38 through lead screw transmission, realizing precise adjustment of the clamping position and meeting the clamping requirements of packaging bags of different sizes.

[0052] A ninth cylinder 42 is fixedly mounted on the fourth movable plate 64 and is movably connected to a clamping block 44 via a shaft 43. The shaft 43 acts as a fulcrum, allowing the clamping block 44 to rotate around it. The drive end of the ninth cylinder 42 is fixedly connected to the clamping block 44. When the ninth cylinder 42 extends, it drives the clamping block 44 to rotate around the shaft 43, causing the clamping block 44 to engage with the side of the fourth movable plate 64 to form a clamping force, firmly securing the packaging bag. During clamping, the contact surface between the clamping block 44 and the packaging bag is rationally designed to ensure stable clamping without damaging the surface of the packaging bag. The second guide rails 39 are symmetrically arranged, and the fourth movable plate 64 is connected to the guide rails via a slider, ensuring symmetrical and synchronous clamping actions and enhancing clamping stability.

[0053] During the operation of the cable ties packaging machine, after the transfer mechanism 5 moves the packaging bag to the corresponding workstation, the first bag clamping mechanism 9 or the second bag clamping mechanism 26 is activated. The eighth cylinder 37 drives the third moving plate 38 to move, bringing the bag clamping mechanism closer to the packaging bag. The first motor 40 adjusts the position of the fourth moving plate 64 through the first lead screw 41, aligning the clamping block 44 with the packaging bag clamping area. The ninth cylinder 42 extends, driving the clamping block 44 to rotate around the shaft 43, working in conjunction with the side of the fourth moving plate 64 to clamp and fix the packaging bag. After clamping is completed, the transfer mechanism 5 is released and reset, allowing for the next round of transfer operations and continuous production.

[0054] This bag clamping mechanism, through a combination of multi-stage cylinders and lead screw drives, achieves flexible adjustment and stable clamping position, effectively adapting to the processing needs of packaging bags of different sizes. The mechanism operates smoothly with uniform clamping force, ensuring that the packaging bags remain fixed during sealing or filling, preventing displacement or deformation. The entire clamping process is highly automated, working in conjunction with the transfer mechanism 5 to significantly improve the overall production efficiency of the cable ties packaging machine.

[0055] Example 5:

[0056] The insertion mechanism 10 of this embodiment includes a tenth cylinder 46, the drive end of which is fixedly mounted with a fixing plate 47. The fixing plate 47 serves as a support base to ensure the stability of the overall structure. An eleventh cylinder 48 is fixedly mounted on the fixing plate 47, which is responsible for driving the insertion and withdrawal of the conduit 51. A connecting block 50 is fixedly connected to the fixing plate 47 via a first optical axis 49. The first optical axis 49 provides a guiding function to ensure that the connecting block 50 maintains linear motion during movement and avoids deviation. The connecting block 50 is fixedly mounted with the conduit 51, which is connected to a vacuum machine for extracting internal air after insertion into the packaging bag.

[0057] During operation, when the packaging bag is transferred to the sealing mechanism 4, the first bag clamping mechanism 9 first clamps and fixes the packaging bag to ensure accurate positioning. Then, the insertion mechanism 10 is activated, and the tenth cylinder 46 drives the fixing plate 47 to move horizontally, adjusting the position of the guide tube 51 to accommodate packaging bags of different sizes. This horizontal adjustment mechanism ensures that the guide tube 51 is precisely aligned with the bag opening, avoiding insertion failure due to changes in packaging bag size. Next, the eleventh cylinder 48 drives the connecting block 50 to move along the first optical axis 49, causing the guide tube 51 to be inserted into the packaging bag. After the guide tube 51 is connected to the vacuum machine, the vacuum machine is activated, drawing air from the packaging bag through the guide tube 51 to achieve the vacuuming process. After vacuuming is completed, the eleventh cylinder 48 reverses its movement, driving the guide tube 51 to be pulled out of the packaging bag, preparing for the subsequent sealing operation.

[0058] In this embodiment, the design of the insertion mechanism 10 emphasizes coordination and adaptability. The horizontal adjustment function of the tenth cylinder 46 allows the mechanism to flexibly handle various packaging bag sizes, while the insertion and withdrawal actions of the eleventh cylinder 48 are precisely controlled by the guidance of the first optical axis 49. The connection between the conduit 51 and the vacuum machine ensures the reliability of the vacuuming process and avoids air residue affecting the sealing quality. The overall structure is compact, operates smoothly, effectively improves sealing efficiency, and reduces manual intervention, meeting the needs of automated production.

[0059] Through continuous operation, the insertion mechanism 10 works in conjunction with other components of the sealing mechanism 4 to ensure that the packaging bag quickly enters the heat-sealing stage after vacuuming. This integrated design not only improves production efficiency but also reduces equipment failure rate, making it suitable for large-scale cable tie packaging applications.

[0062] In this embodiment, both the first pressure plate 14 and the second pressure plate 16 are fixedly equipped with rubber parts 52. These rubber parts 52 are made of elastic material and have good cushioning and anti-slip properties. When the packaging bag is transferred to the sealing mechanism 4, the first bag clamping mechanism 9 first clamps and fixes the packaging bag to ensure its accurate position. Subsequently, the tube insertion mechanism 10 inserts the conduit 51 into the packaging bag. The conduit 51 is connected to the vacuum machine for subsequent vacuuming operations. The pressing mechanism 8 is activated, and the symmetrically arranged third cylinders 15 extend simultaneously, driving the second pressure plate 16 to move towards the opening of the packaging bag. Because the second pressure plate 16 is equipped with rubber parts 52, when the second pressure plate 16 presses the bag opening, the rubber parts 52 can evenly distribute the pressure, avoiding local stress concentration, thereby effectively preventing the packaging bag from being crushed or deformed during the pressing process. The softness of the rubber parts 52 can also adapt to the unevenness of the packaging bag surface, ensuring a reliable sealing effect.

[0063] The heat-sealing mechanism 7 is then activated, with the first cylinder 11 and the second cylinder 12 working together to drive the heating element 13 and the first pressure plate 14 towards the bag opening. A rubber component 52 is also installed on the first pressure plate 14. When the first pressure plate 14 cooperates with the heating element 13 to press the bag opening, the rubber component 52 acts as a buffer, preventing damage to the packaging bag from direct contact with the rigid pressure plate during the heat-sealing process. The heating element 13 fuses the bag opening via heat sealing, and the presence of the rubber component 52 ensures uniform pressure transmission, preventing the bag opening from being punctured or torn at high temperatures. After heat sealing is completed, the pressing mechanism 8 and the heat-sealing mechanism 7 are reset, and the packaging bag is transferred to the next workstation by the transfer mechanism 5.

[0064] During operation, the first gripping mechanism 19, the second gripping mechanism 20, and the third gripping mechanism 21 are located at different workstations, performing the task of gripping and transferring packaging bags. These gripping mechanisms have cushioning rubber blocks installed on their top blocks 23. When the fifth cylinder 22 drives the top blocks 23 to clamp the packaging bag, the cushioning rubber blocks absorb the impact force, preventing the packaging bag from being crushed or scratched during gripping and transfer. Through continuous operation, the packaging bags are synchronously transferred between different processing stations, improving production efficiency. Simultaneously, the coordinated use of the rubber parts 52 and the cushioning rubber blocks ensures the integrity and quality of the packaging bags throughout the sealing process.

[0065] In this embodiment, the sealing mechanism 4 achieves multiple protections for the packaging bag by fixing rubber parts 52 to the first pressure plate 14 and the second pressure plate 16, combined with the buffer rubber block of the gripping mechanism. The elastic properties of the rubber parts 52 disperse pressure during compression and heat sealing, preventing damage to the packaging bag due to mechanical action; the buffer rubber block provides flexible contact during gripping and transfer, reducing wear on the packaging bag. This design not only improves the reliability of the sealing operation but also extends the service life of the packaging bag, making it suitable for various types of cable tie packaging needs. The entire mechanism has a compact structure, stable operation, and effectively improves the automation level and production efficiency of cable tie packaging.

[0066] Example 7:

[0067] The bagging mechanism 3 in this embodiment also includes a bag-shaking mechanism 53, which consists of a second lifting mechanism 54 and a shaking mechanism 55. The shaking mechanism 55 includes a mounting frame 56, on which a second motor 57 is fixedly mounted. The drive end of the second motor 57 is fixedly connected to an eccentric arm 58, which is rigidly connected to a shaking plate 60 via a connecting rod 59. A support member 61 is fixedly mounted on the shaking plate 60 to support the packaging bag. The shaking plate 60 is movably connected to the mounting frame 56 via a second optical axis to ensure that the shaking plate 60 can move smoothly back and forth under the drive of the second motor 57. When the packaging bag is inserted with a cable tie, the second lifting mechanism 54 drives the shaking mechanism 55 to descend to an appropriate position, and the second motor 57 starts. Through the transmission of the eccentric arm 58 and the connecting rod 59, the shaking plate 60 generates high-frequency vibration, causing the packaging bag on the support member 61 to shake synchronously. This process causes the cable ties inside the packaging bag to quickly sink to the bottom under the action of gravity, preventing the cable ties from getting stuck in the bag opening area, thus ensuring that the bag opening is flat and unobstructed during subsequent sealing operations, improving sealing quality and efficiency.

[0068] During the operation of the bag-shaking mechanism 53, the rotational motion of the second motor 57 is converted into periodic oscillation through the eccentric arm 58. The connecting rod 59 transmits this oscillation to the shaking plate 60, causing the shaking plate 60 to reciprocate linearly along the second optical axis. The support 61 moves synchronously with the shaking plate 60, applying a continuous shaking effect to the packaging bag. Under the combined action of inertia and gravity, the tie inside the packaging bag moves downward and is evenly distributed to the bottom of the bag. This design effectively solves the problem of tie straps potentially remaining at the bag opening after filling, preventing the tie straps from interfering with the heat-sealing and pressing process during sealing, and ensuring a firm and reliable seal. The bag-shaking mechanism 53 has a compact structure, stable operation, and coordinates well with other components of the bag-filling mechanism 3, improving the automation level of the overall packaging process.

[0069] The coordinated operation of the bag-shaking mechanism 53 and the sealing mechanism 4 further optimizes packaging efficiency. After the bag-shaking mechanism 53 completes its shaking, the transfer mechanism 5 moves the packaging bag to the sealing station. The first bag-clamping mechanism 9 of the sealing mechanism 4 clamps and fixes the packaging bag, and the tube insertion mechanism 10 inserts the tube 51 to perform vacuuming. The symmetrical third cylinder 15 of the pressing mechanism 8 drives the second pressure plate 16 to press the bag opening to ensure sealing. After the vacuum machine removes the air, the first cylinder 11 and the second cylinder 12 of the heat-sealing mechanism 7 drive the heating element 13 and the first pressure plate 14 to press the bag opening, completing the sealing through heat sealing. The pre-treatment of the bag-shaking mechanism 53 ensures that there is no interference from the tie at the bag opening, making the pressing and heat sealing processes smoother and avoiding sealing failure or equipment failure caused by improper tie placement, thereby significantly improving production efficiency and product qualification rate.

[0070] Throughout this embodiment, the design of the bag-shaking mechanism 53 fully considers the physical characteristics of the tie inside the packaging bag, achieving rapid settling of the tie through mechanical vibration. The driving method of the second motor 57 ensures the controllability of the shaking frequency and amplitude. The transmission structure of the eccentric arm 58 and connecting rod 59 is simple, reliable, and easy to maintain. The movable connection of the second optical shaft reduces friction and wear, extending the service life of the equipment. The combination of the bag-shaking mechanism 53 and the second lifting mechanism 54 allows the shaking position to be flexibly adjusted according to the size of the packaging bag, adapting to the packaging needs of different specifications of tie. This embodiment not only solves common problems in actual production but also reduces manual intervention through automation, demonstrating the high efficiency and practicality of the packaging equipment.
